* ARM DynamIQ Shared Unit (DSU) Performance Monitor Unit (PMU)
ARM DyanmIQ Shared Unit (DSU) integrates one or more CPU cores
with a shared L3 memory system, control logic and external interfaces to
form a multicore cluster. The PMU enables to gather various statistics on
the operations of the DSU. The PMU provides independent 32bit counters that
can count any of the supported events, along with a 64bit cycle counter.
The PMU is accessed via CPU system registers and has no MMIO component.
** DSU PMU required properties:
- compatible : should be one of :
"arm,dsu-pmu"
- interrupts : Exactly 1 SPI must be listed.
- cpus : List of phandles for the CPUs connected to this DSU instance.
** Example:
dsu-pmu-0 {
compatible = "arm,dsu-pmu";
interrupts = <GIC_SPI 02 IRQ_TYPE_LEVEL_HIGH>;
cpus = <&cpu_0>, <&cpu_1>;
};

* Samsung Exynos5260 Clock Controller
Exynos5260 has 13 clock controllers which are instantiated
independently from the device-tree. These clock controllers
generate and supply clocks to various hardware blocks within
the SoC.
Each clock is assigned an identifier and client nodes can use
this identifier to specify the clock which they consume. All
available clocks are defined as preprocessor macros in
dt-bindings/clock/exynos5260-clk.h header and can be used in
device tree sources.
External clocks:
There are several clocks that are generated outside the SoC. It
is expected that they are defined using standard clock bindings
with following clock-output-names:
- "fin_pll" - PLL input clock from XXTI
- "xrtcxti" - input clock from XRTCXTI
- "ioclk_pcm_extclk" - pcm external operation clock
- "ioclk_spdif_extclk" - spdif external operation clock
- "ioclk_i2s_cdclk" - i2s0 codec clock
Phy clocks:
There are several clocks which are generated by specific PHYs.
These clocks are fed into the clock controller and then routed to
the hardware blocks. These clocks are defined as fixed clocks in the
driver with following names:
- "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
- "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
- "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
- "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
- "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
- "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
- "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
- "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
- "phyclk_dptx_phy_clk_div2"
- "phyclk_mipi_dphy_4l_m_rxclkesc0"
- "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
- "phyclk_usbhost20_phy_freeclk"
- "phyclk_usbhost20_phy_clk48mohci"
- "phyclk_usbdrd30_udrd30_pipe_pclk"
- "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock

* Samsung Exynos5410 Clock Controller
The Exynos5410 clock controller generates and supplies clock to various
controllers within the Exynos5410 SoC.
Required Properties:
- compatible: should be "samsung,exynos5410-clock"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- clocks: should contain an entry specifying the root clock from external
oscillator supplied through XXTI or XusbXTI pin. This clock should be
defined using standard clock bindings with "fin_pll" clock-output-name.
That clock is being passed internally to the 9 PLLs.
All available clocks are defined as preprocessor macros in
dt-bindings/clock/exynos5410.h header and can be used in device
tree sources.
Example 1: An example of a clock controller node is listed below.
fin_pll: xxti {
compatible = "fixed-clock";
clock-frequency = <24000000>;
clock-output-names = "fin_pll";
#clock-cells = <0>;
};
clock: clock-controller@10010000 {
compatible = "samsung,exynos5410-clock";
reg = <0x10010000 0x30000>;
#clock-cells = <1>;
clocks = <&fin_pll>;
};
Example 2: UART controller node that consumes the clock generated by the clock
controller. Refer to the standard clock bindings for information
about 'clocks' and 'clock-names' property.

* Samsung Exynos7 Clock Controller
Exynos7 clock controller has various blocks which are instantiated
independently from the device-tree. These clock controllers
generate and supply clocks to various hardware blocks within
the SoC.
Each clock is assigned an identifier and client nodes can use
this identifier to specify the clock which they consume. All
available clocks are defined as preprocessor macros in
dt-bindings/clock/exynos7-clk.h header and can be used in
device tree sources.
External clocks:
There are several clocks that are generated outside the SoC. It
is expected that they are defined using standard clock bindings
with following clock-output-names:
- "fin_pll" - PLL input clock from XXTI
Required Properties for Clock Controller:
- compatible: clock controllers will use one of the following
compatible strings to indicate the clock controller
functionality.

Expected external clocks, defined in DTS as fixed-rate clocks with a matching
name::
- "fin_pll" - PLL input clock from XXTI
- "xrtcxti" - input clock from XRTCXTI
- "ioclk_pcm_extclk" - pcm external operation clock
- "ioclk_spdif_extclk" - spdif external operation clock
- "ioclk_i2s_cdclk" - i2s0 codec clock
Phy clocks::
There are several clocks which are generated by specific PHYs. These clocks
are fed into the clock controller and then routed to the hardware blocks.
These clocks are defined as fixed clocks in the driver with following names::
- "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
- "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
- "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
- "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
- "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
- "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
- "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
- "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
- "phyclk_dptx_phy_clk_div2"
- "phyclk_mipi_dphy_4l_m_rxclkesc0"
- "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
- "phyclk_usbhost20_phy_freeclk"
- "phyclk_usbhost20_phy_clk48mohci"
- "phyclk_usbdrd30_udrd30_pipe_pclk"
- "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
All available clocks are defined as preprocessor macros in
include/dt-bindings/clock/exynos5260-clk.h header.

* Samsung S5P6442/S5PC110/S5PV210 Clock Controller
Samsung S5P6442, S5PC110 and S5PV210 SoCs contain integrated clock
controller, which generates and supplies clock to various controllers
within the SoC.
Required Properties:
- compatible: should be one of following:
- "samsung,s5pv210-clock" : for clock controller of Samsung
S5PC110/S5PV210 SoCs,
- "samsung,s5p6442-clock" : for clock controller of Samsung
S5P6442 SoC.
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
All available clocks are defined as preprocessor macros in
dt-bindings/clock/s5pv210.h header and can be used in device tree sources.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xxti": external crystal oscillator connected to XXTI and XXTO pins of
the SoC,
- "xusbxti": external crystal oscillator connected to XUSBXTI and XUSBXTO
pins of the SoC,
A subset of above clocks available on given board shall be specified in
board device tree, including the system base clock, as selected by XOM[0]
pin of the SoC. Refer to generic fixed rate clock bindings
documentation[1] for more information how to specify these clocks.
[1] Documentation/devicetree/bindings/clock/fixed-clock.yaml
Example: Clock controller node:
clock: clock-controller@7e00f000 {
compatible = "samsung,s5pv210-clock";
reg = <0x7e00f000 0x1000>;
#clock-cells = <1>;
};
Example: Required external clocks:
xxti: clock-xxti {
compatible = "fixed-clock";
clock-output-names = "xxti";
clock-frequency = <24000000>;
#clock-cells = <0>;
};
xusbxti: clock-xusbxti {
compatible = "fixed-clock";
clock-output-names = "xusbxti";
clock-frequency = <24000000>;
#clock-cells = <0>;
};
Example: UART controller node that consumes the clock generated by the clock
controller (refer to the standard clock bindings for information about
"clocks" and "clock-names" properties):
uart0: serial@e2900000 {
compatible = "samsung,s5pv210-uart";
reg = <0xe2900000 0x400>;
interrupt-parent = <&vic1>;
interrupts = <10>;
clock-names = "uart", "clk_uart_baud0",
"clk_uart_baud1";
clocks = <&clocks UART0>, <&clocks UART0>,
<&clocks SCLK_UART0>;

Broadcom STB "UPG GIO" GPIO controller
The controller's registers are organized as sets of eight 32-bit
registers with each set controlling a bank of up to 32 pins. A single
interrupt is shared for all of the banks handled by the controller.
Required properties:
- compatible:
Must be "brcm,brcmstb-gpio"
- reg:
Define the base and range of the I/O address space containing
the brcmstb GPIO controller registers
- #gpio-cells:
Should be <2>. The first cell is the pin number (within the controller's
pin space), and the second is used for the following:
bit[0]: polarity (0 for active-high, 1 for active-low)
- gpio-controller:
Specifies that the node is a GPIO controller.
- brcm,gpio-bank-widths:
Number of GPIO lines for each bank. Number of elements must
correspond to number of banks suggested by the 'reg' property.
Optional properties:
- interrupts:
The interrupt shared by all GPIO lines for this controller.
- interrupts-extended:
Alternate form of specifying interrupts and parents that allows for
multiple parents. This takes precedence over 'interrupts' and
'interrupt-parent'. Wakeup-capable GPIO controllers often route their
wakeup interrupt lines through a different interrupt controller than the
primary interrupt line, making this property necessary.
- #interrupt-cells:
Should be <2>. The first cell is the GPIO number, the second should specify
flags. The following subset of flags is supported:
- bits[3:0] trigger type and level flags
1 = low-to-high edge triggered
2 = high-to-low edge triggered
4 = active high level-sensitive
8 = active low level-sensitive
Valid combinations are 1, 2, 3, 4, 8.
See also Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- interrupt-controller:
Marks the device node as an interrupt controller
- wakeup-source:
GPIOs for this controller can be used as a wakeup source
Example:
upg_gio: gpio@f040a700 {
#gpio-cells = <2>;
#interrupt-cells = <2>;
compatible = "brcm,bcm7445-gpio", "brcm,brcmstb-gpio";
gpio-controller;
interrupt-controller;
reg = <0xf040a700 0x80>;
interrupt-parent = <&irq0_intc>;
interrupts = <0x6>;
brcm,gpio-bank-widths = <32 32 32 24>;
};
upg_gio_aon: gpio@f04172c0 {
#gpio-cells = <2>;
#interrupt-cells = <2>;
compatible = "brcm,bcm7445-gpio", "brcm,brcmstb-gpio";
gpio-controller;
interrupt-controller;
reg = <0xf04172c0 0x40>;
interrupt-parent = <&irq0_aon_intc>;
interrupts = <0x6>;
interrupts-extended = <&irq0_aon_intc 0x6>,
<&aon_pm_l2_intc 0x5>;
wakeup-source;
brcm,gpio-bank-widths = <18 4>;

Required properties:
- compatible: i2c-mux-gpio
- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
port is connected to.
- mux-gpios: list of gpios used to control the muxer
* Standard I2C mux properties. See i2c-mux.yaml in this directory.
* I2C child bus nodes. See i2c-mux.yaml in this directory.
Optional properties:
- idle-state: value to set the muxer to when idle. When no value is
given, it defaults to the last value used.
For each i2c child node, an I2C child bus will be created. They will
be numbered based on their order in the device tree.
Whenever an access is made to a device on a child bus, the value set
in the relevant node's reg property will be output using the list of
GPIOs, the first in the list holding the least-significant value.
If an idle state is defined, using the idle-state (optional) property,
whenever an access is not being made to a device on a child bus, the
GPIOs will be set according to the idle value.
If an idle state is not defined, the most recently used value will be
left programmed into hardware whenever no access is being made to a
device on a child bus.

Pinctrl-based I2C Bus Mux
This binding describes an I2C bus multiplexer that uses pin multiplexing to
route the I2C signals, and represents the pin multiplexing configuration
using the pinctrl device tree bindings.

| dev | | dev |
+------------------------+ +-----+ +-----+

| | | | |
+------------------------+ +-----+ +-----+ +-----+
| dev | | dev | | dev |
+-----+ +-----+ +-----+
Required properties:
- compatible: i2c-mux-pinctrl
- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
port is connected to.
Also required are:
* Standard pinctrl properties that specify the pin mux state for each child
bus. See ../pinctrl/pinctrl-bindings.txt.
* Standard I2C mux properties. See i2c-mux.yaml in this directory.
* I2C child bus nodes. See i2c-mux.yaml in this directory.
For each named state defined in the pinctrl-names property, an I2C child bus
will be created. I2C child bus numbers are assigned based on the index into
the pinctrl-names property.
The only exception is that no bus will be created for a state named "idle". If
such a state is defined, it must be the last entry in pinctrl-names. For
example:
pinctrl-names = "ddc", "pta", "idle" -> ddc = bus 0, pta = bus 1
pinctrl-names = "ddc", "idle", "pta" -> Invalid ("idle" not last)
pinctrl-names = "idle", "ddc", "pta" -> Invalid ("idle" not last)
Whenever an access is made to a device on a child bus, the relevant pinctrl
state will be programmed into hardware.
If an idle state is defined, whenever an access is not being made to a device
on a child bus, the idle pinctrl state will be programmed into hardware.
If an idle state is not defined, the most recently used pinctrl state will be
left programmed into hardware whenever no access is being made of a device on
a child bus.
Example:
i2cmux {
compatible = "i2c-mux-pinctrl";
#address-cells = <1>;
#size-cells = <0>;
i2c-parent = <&i2c1>;
pinctrl-names = "ddc", "pta", "idle";

NVIDIA Tegra186 BPMP I2C controller
In Tegra186, the BPMP (Boot and Power Management Processor) owns certain HW
devices, such as the I2C controller for the power management I2C bus. Software
running on other CPUs must perform IPC to the BPMP in order to execute
transactions on that I2C bus. This binding describes an I2C bus that is
accessed in such a fashion.
The BPMP I2C node must be located directly inside the main BPMP node. See
../firmware/nvidia,tegra186-bpmp.txt for details of the BPMP binding.
This node represents an I2C controller. See ../i2c/i2c.txt for details of the
core I2C binding.
Required properties:
- compatible:
Array of strings.
One of:
- "nvidia,tegra186-bpmp-i2c".
- #address-cells: Address cells for I2C device address.
Single-cell integer.
Must be <1>.
- #size-cells:
Single-cell integer.
Must be <0>.
- nvidia,bpmp-bus-id:
Single-cell integer.
Indicates the I2C bus number this DT node represent, as defined by the
BPMP firmware.
Example:
bpmp {

i2c {
compatible = "nvidia,tegra186-bpmp-i2c";
#address-cells = <1>;
#size-cells = <0>;
nvidia,bpmp-bus-id = <5>;

NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
Required properties:
- compatible : For Tegra20, must be one of "nvidia,tegra20-i2c-dvc" or
"nvidia,tegra20-i2c". For Tegra30, must be "nvidia,tegra30-i2c".
For Tegra114, must be "nvidia,tegra114-i2c". Otherwise, must be
"nvidia,<chip>-i2c", plus at least one of the above, where <chip> is
tegra124, tegra132, or tegra210.
Details of compatible are as follows:
nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
controller. This only support master mode of I2C communication. Register
interface/offset and interrupts handling are different than generic I2C
controller. Driver of DVC I2C controller is only compatible with
"nvidia,tegra20-i2c-dvc".
nvidia,tegra20-i2c: Tegra20 has 4 generic I2C controller. This can support
master and slave mode of I2C communication. The i2c-tegra driver only
support master mode of I2C communication. Driver of I2C controller is
only compatible with "nvidia,tegra20-i2c".
nvidia,tegra30-i2c: Tegra30 has 5 generic I2C controller. This controller is
very much similar to Tegra20 I2C controller with additional feature:
Continue Transfer Support. This feature helps to implement M_NO_START
as per I2C core API transfer flags. Driver of I2C controller is
compatible with "nvidia,tegra30-i2c" to enable the continue transfer
support. This is also compatible with "nvidia,tegra20-i2c" without
continue transfer support.
nvidia,tegra114-i2c: Tegra114 has 5 generic I2C controller. This controller is
very much similar to Tegra30 I2C controller with some hardware
modification:
- Tegra30/Tegra20 I2C controller has 2 clock source called div-clk and
fast-clk. Tegra114 has only one clock source called as div-clk and
hence clock mechanism is changed in I2C controller.
- Tegra30/Tegra20 I2C controller has enabled per packet transfer by
default and there is no way to disable it. Tegra114 has this
interrupt disable by default and SW need to enable explicitly.
Due to above changes, Tegra114 I2C driver makes incompatible with
previous hardware driver. Hence, tegra114 I2C controller is compatible
with "nvidia,tegra114-i2c".
nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is on host1x bus
and is part of VE power domain and typically used for camera use-cases.
This VI I2C controller is mostly compatible with the programming model
of the regular I2C controllers with a few exceptions. The I2C registers
start at an offset of 0xc00 (instead of 0), registers are 16 bytes
apart (rather than 4) and the controller does not support slave mode.
- reg: Should contain I2C controller registers physical address and length.
- interrupts: Should contain I2C controller interrupts.
- address-cells: Address cells for I2C device address.
- size-cells: Size of the I2C device address.
- clocks: Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
- clock-names: Must include the following entries:
Tegra20/Tegra30:
- div-clk
- fast-clk
Tegra114:
- div-clk
Tegra210:
- div-clk
- slow (only for nvidia,tegra210-i2c-vi compatible node)
- resets: Must contain an entry for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: Must include the following entries:
- i2c
- power-domains: Only for nvidia,tegra210-i2c-vi compatible node and must
include venc powergate node as vi i2c is part of VE power domain.
tegra210-i2c-vi:
- pd_venc
- dmas: Must contain an entry for each entry in clock-names.
See ../dma/dma.txt for details.
- dma-names: Must include the following entries:
- rx
- tx
Example:
i2c@7000c000 {
compatible = "nvidia,tegra20-i2c";
reg = <0x7000c000 0x100>;
interrupts = <0 38 0x04>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&tegra_car 12>, <&tegra_car 124>;
clock-names = "div-clk", "fast-clk";
resets = <&tegra_car 12>;
reset-names = "i2c";
dmas = <&apbdma 16>, <&apbdma 16>;
dma-names = "rx", "tx";

Transfer Support. This feature helps to implement M_NO_START as per
I2C core API transfer flags. Driver of I2C controller is compatible
with "nvidia,tegra30-i2c" to enable the continue transfer support.
This is also compatible with "nvidia,tegra20-i2c" without continue
transfer support.

Tegra114 has 5 generic I2C controllers. This controller is very much
similar to Tegra30 I2C controller with some hardware modification:
- Tegra30/Tegra20 I2C controller has 2 clock source called div-clk
and fast-clk. Tegra114 has only one clock source called as
div-clk and hence clock mechanism is changed in I2C controller.
- Tegra30/Tegra20 I2C controller has enabled per packet transfer
by default and there is no way to disable it. Tegra114 has this
interrupt disable by default and SW need to enable explicitly.
Due to above changes, Tegra114 I2C driver makes incompatible with
previous hardware driver. Hence, Tegra114 I2C controller is
compatible with "nvidia,tegra114-i2c".

Tegra210 has one I2C controller that is on host1x bus and is part of
the VE power domain and typically used for camera use-cases. This VI
I2C controller is mostly compatible with the programming model of
the regular I2C controllers with a few exceptions. The I2C registers
start at an offset of 0xc00 (instead of 0), registers are 16 bytes
apart (rather than 4) and the controller does not support slave
mode.

support for 64 KiB transactions whereas earlier chips supported no
more than 4 KiB per transactions.

* PWM vibrator device tree bindings
Registers a PWM device as vibrator. It is expected, that the vibrator's
strength increases based on the duty cycle of the enable PWM channel
(100% duty cycle meaning strongest vibration, 0% meaning no vibration).
The binding supports an optional direction PWM channel, that can be
driven at fixed duty cycle. If available this is can be used to increase
the vibration effect of some devices.
Required properties:
- compatible: should contain "pwm-vibrator"
- pwm-names: Should contain "enable" and optionally "direction"
- pwms: Should contain a PWM handle for each entry in pwm-names
Optional properties:
- vcc-supply: Phandle for the regulator supplying power
- direction-duty-cycle-ns: Duty cycle of the direction PWM channel in
nanoseconds, defaults to 50% of the channel's
period.
Example from Motorola Droid 4:
&omap4_pmx_core {
vibrator_direction_pin: pinmux_vibrator_direction_pin {
pinctrl-single,pins = <
OMAP4_IOPAD(0x1ce, PIN_OUTPUT | MUX_MODE1) /* dmtimer8_pwm_evt (gpio_27) */
>;
};
vibrator_enable_pin: pinmux_vibrator_enable_pin {
pinctrl-single,pins = <
OMAP4_IOPAD(0X1d0, PIN_OUTPUT | MUX_MODE1) /* dmtimer9_pwm_evt (gpio_28) */
>;
};
};

Broadcom BCM3380-style Level 1 / Level 2 interrupt controller
This interrupt controller shows up in various forms on many BCM338x/BCM63xx
chipsets. It has the following properties:
- outputs a single interrupt signal to its interrupt controller parent
- contains one or more enable/status word pairs, which often appear at
different offsets in different blocks
- no atomic set/clear operations
Required properties:
- compatible: should be "brcm,bcm3380-l2-intc"
- reg: specifies one or more enable/status pairs, in the following format:
<enable_reg 0x4 status_reg 0x4>...
- interrupt-controller: identifies the node as an interrupt controller
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
source, should be 1.
- interrupts: specifies the interrupt line in the interrupt-parent controller
node, valid values depend on the type of parent interrupt controller
Optional properties:
- brcm,irq-can-wake: if present, this means the L2 controller can be used as a
wakeup source for system suspend/resume.
Example:
irq0_intc: interrupt-controller@10000020 {
compatible = "brcm,bcm3380-l2-intc";
reg = <0x10000024 0x4 0x1000002c 0x4>,

Broadcom BCM7038-style Level 1 interrupt controller
This block is a first level interrupt controller that is typically connected
directly to one of the HW INT lines on each CPU. Every BCM7xxx set-top chip
since BCM7038 has contained this hardware.
Key elements of the hardware design include:
- 64, 96, 128, or 160 incoming level IRQ lines
- Most onchip peripherals are wired directly to an L1 input
- A separate instance of the register set for each CPU, allowing individual
peripheral IRQs to be routed to any CPU
- Atomic mask/unmask operations
- No polarity/level/edge settings
- No FIFO or priority encoder logic; software is expected to read all
2-5 status words to determine which IRQs are pending
Required properties:
- compatible: should be "brcm,bcm7038-l1-intc"
- reg: specifies the base physical address and size of the registers;
the number of supported IRQs is inferred from the size argument
- interrupt-controller: identifies the node as an interrupt controller
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
source, should be 1.
- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
node; valid values depend on the type of parent interrupt controller
Optional properties:
- brcm,irq-can-wake: If present, this means the L1 controller can be used as a
wakeup source for system suspend/resume.
Optional properties:
- brcm,int-fwd-mask: if present, a bit mask to indicate which interrupts
have already been configured by the firmware and should be left unmanaged.
This should have one 32-bit word per status/set/clear/mask group.
If multiple reg ranges and interrupt-parent entries are present on an SMP
system, the driver will allow IRQ SMP affinity to be set up through the
/proc/irq/ interface. In the simplest possible configuration, only one
reg range and one interrupt-parent is needed.
Example:
periph_intc: periph_intc@1041a400 {
compatible = "brcm,bcm7038-l1-intc";
reg = <0x1041a400 0x30 0x1041a600 0x30>;

#interrupt-cells = <1>;
interrupt-parent = <&cpu_intc>;

Broadcom BCM7120-style Level 2 interrupt controller
This interrupt controller hardware is a second level interrupt controller that
is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based
platforms. It can be found on BCM7xxx products starting with BCM7120.
Such an interrupt controller has the following hardware design:
- outputs multiple interrupts signals towards its interrupt controller parent
- controls how some of the interrupts will be flowing, whether they will
directly output an interrupt signal towards the interrupt controller parent,
or if they will output an interrupt signal at this 2nd level interrupt
controller, in particular for UARTs
- has one 32-bit enable word and one 32-bit status word
- no atomic set/clear operations
- not all bits within the interrupt controller actually map to an interrupt
The typical hardware layout for this controller is represented below:
2nd level interrupt line Outputs for the parent controller (e.g: ARM GIC)
0 -----[ MUX ] ------------|==========> GIC interrupt 75
\-----------\
|
1 -----[ MUX ] --------)---|==========> GIC interrupt 76

Required properties:
- compatible: should be "brcm,bcm7120-l2-intc"
- reg: specifies the base physical address and size of the registers
- interrupt-controller: identifies the node as an interrupt controller
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
source, should be 1.
- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
node, valid values depend on the type of parent interrupt controller
- brcm,int-map-mask: 32-bits bit mask describing how many and which interrupts
are wired to this 2nd level interrupt controller, and how they match their
respective interrupt parents. Should match exactly the number of interrupts
specified in the 'interrupts' property.
Optional properties:
- brcm,irq-can-wake: if present, this means the L2 controller can be used as a
wakeup source for system suspend/resume.
- brcm,int-fwd-mask: if present, a bit mask to configure the interrupts which
have a mux gate, typically UARTs. Setting these bits will make their
respective interrupt outputs bypass this 2nd level interrupt controller
completely; it is completely transparent for the interrupt controller
parent. This should have one 32-bit word per enable/status pair.
Example:
irq0_intc: interrupt-controller@f0406800 {
compatible = "brcm,bcm7120-l2-intc";
interrupt-parent = <&intc>;
#interrupt-cells = <1>;

LEDs connected to Broadcom BCM6328 controller
This controller is present on BCM6318, BCM6328, BCM6362 and BCM63268.
In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
However, on some devices there are Serial LEDs (LEDs connected to a 74x164
controller), which can either be controlled by software (exporting the 74x164
as spi-gpio. See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml),
or by hardware using this driver.
Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
controlled, so the only chance to keep them working is by using this driver.
BCM6328 LED controller has a HWDIS register, which controls whether a LED
should be controlled by a hardware signal instead of the MODE register value,
with 0 meaning hardware control enabled and 1 hardware control disabled. This
is usually 1:1 for hardware to LED signals, but through the activity/link
registers you have some limited control over rerouting the LEDs (as
explained later in brcm,link-signal-sources). Even if a LED is hardware
controlled you are still able to make it blink or light it up if it isn't,
but you can't turn it off if the hardware decides to light it up. For this
reason, hardware controlled LEDs aren't registered as LED class devices.
Required properties:
- compatible : should be "brcm,bcm6328-leds".
- #address-cells : must be 1.
- #size-cells : must be 0.
- reg : BCM6328 LED controller address and size.
Optional properties:
- brcm,serial-leds : Boolean, enables Serial LEDs.
Default : false
- brcm,serial-mux : Boolean, enables Serial LEDs multiplexing.
Default : false
- brcm,serial-clk-low : Boolean, makes clock signal active low.
Default : false
- brcm,serial-dat-low : Boolean, makes data signal active low.
Default : false
- brcm,serial-shift-inv : Boolean, inverts Serial LEDs shift direction.
Default : false
Each LED is represented as a sub-node of the brcm,bcm6328-leds device.
LED sub-node required properties:
- reg : LED pin number (only LEDs 0 to 23 are valid).
LED sub-node optional properties:
a) Optional properties for sub-nodes related to software controlled LEDs:
- label : see Documentation/devicetree/bindings/leds/common.txt
- active-low : Boolean, makes LED active low.
Default : false
- default-state : see
Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger : see
Documentation/devicetree/bindings/leds/common.txt
b) Optional properties for sub-nodes related to hardware controlled LEDs:
- brcm,hardware-controlled : Boolean, makes this LED hardware controlled.
Default : false
- brcm,link-signal-sources : An array of hardware link
signal sources. Up to four link hardware signals can get muxed into
these LEDs. Only valid for LEDs 0 to 7, where LED signals 0 to 3 may
be muxed to LEDs 0 to 3, and signals 4 to 7 may be muxed to LEDs
4 to 7. A signal can be muxed to more than one LED, and one LED can
have more than one source signal.
- brcm,activity-signal-sources : An array of hardware activity
signal sources. Up to four activity hardware signals can get muxed into
these LEDs. Only valid for LEDs 0 to 7, where LED signals 0 to 3 may
be muxed to LEDs 0 to 3, and signals 4 to 7 may be muxed to LEDs
4 to 7. A signal can be muxed to more than one LED, and one LED can
have more than one source signal.

title: Quad GMSL2 to CSI-2 Deserializer with GMSL1 Compatibility
maintainers:
- Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
description: |
The MAX96712 deserializer converts GMSL2 or GMSL1 serial inputs into MIPI
CSI-2 D-PHY or C-PHY formatted outputs. The device allows each link to
simultaneously transmit bidirectional control-channel data while forward
video transmissions are in progress. The MAX96712 can accommodate as many as
four remotely located sensors using industry-standard coax or STP
interconnects.
Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the
forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the
MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1
serializers or operate up to 3.12Gbps with GMSL2 serializers in GMSL1 mode.

Required properties:
- compatible: should contain one of "brcm,genet-v1", "brcm,genet-v2",
"brcm,genet-v3", "brcm,genet-v4", "brcm,genet-v5", "brcm,bcm2711-genet-v5" or
"brcm,bcm7712-genet-v5".
- reg: address and length of the register set for the device
- interrupts and/or interrupts-extended: must be two cells, the first cell
is the general purpose interrupt line, while the second cell is the

Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs.
This MDIO bus multiplexer defines buses that could be internal as well as
external to SoCs and could accept MDIO transaction compatible to C-22 or
C-45 Clause. When child bus is selected, one needs to select these two
properties as well to generate desired MDIO transaction on appropriate bus.
Required properties in addition to the generic multiplexer properties:
MDIO multiplexer node:
- compatible: brcm,mdio-mux-iproc.
Every non-ethernet PHY requires a compatible so that it could be probed based
on this compatible string.
Optional properties:
- clocks: phandle of the core clock which drives the mdio block.
Additional information regarding generic multiplexer properties can be found
at- Documentation/devicetree/bindings/net/mdio-mux.yaml

* Broadcom BCM7xxx Ethernet Systemport Controller (SYSTEMPORT)
Required properties:
- compatible: should be one of:
"brcm,systemport-v1.00"
"brcm,systemportlite-v1.00" or
"brcm,systemport"
- reg: address and length of the register set for the device.
- interrupts: interrupts for the device, first cell must be for the rx
interrupts, and the second cell should be for the transmit queues. An
optional third interrupt cell for Wake-on-LAN can be specified
- local-mac-address: Ethernet MAC address (48 bits) of this adapter
- phy-mode: Should be a string describing the PHY interface to the
Ethernet switch/PHY, see Documentation/devicetree/bindings/net/ethernet.txt
- fixed-link: see Documentation/devicetree/bindings/net/fixed-link.txt for
the property specific details
Optional properties:
- systemport,num-tier2-arb: number of tier 2 arbiters, an integer
- systemport,num-tier1-arb: number of tier 1 arbiters, an integer
- systemport,num-txq: number of HW transmit queues, an integer
- systemport,num-rxq: number of HW receive queues, an integer
- clocks: When provided, must be two phandles to the functional clocks nodes of
the SYSTEMPORT block. The first phandle is the main SYSTEMPORT clock used
during normal operation, while the second phandle is the Wake-on-LAN clock.
- clock-names: When provided, names of the functional clock phandles, first
name should be "sw_sysport" and second should be "sw_sysportwol".
Example:
ethernet@f04a0000 {
compatible = "brcm,systemport-v1.00";
reg = <0xf04a0000 0x4650>;
local-mac-address = [ 00 11 22 33 44 55 ];
fixed-link = <0 1 1000 0 0>;

* Broadcom iProc PCIe controller with the platform bus interface
Required properties:
- compatible:
"brcm,iproc-pcie" for the first generation of PAXB based controller,
used in SoCs including NSP, Cygnus, NS2, and Pegasus
"brcm,iproc-pcie-paxb-v2" for the second generation of PAXB-based
controllers, used in Stingray
"brcm,iproc-pcie-paxc" for the first generation of PAXC based
controller, used in NS2
"brcm,iproc-pcie-paxc-v2" for the second generation of PAXC based
controller, used in Stingray
PAXB-based root complex is used for external endpoint devices. PAXC-based
root complex is connected to emulated endpoint devices internal to the ASIC
- reg: base address and length of the PCIe controller I/O register space
- #interrupt-cells: set to <1>
- interrupt-map-mask and interrupt-map, standard PCI properties to define the
mapping of the PCIe interface to interrupt numbers
- linux,pci-domain: PCI domain ID. Should be unique for each host controller
- bus-range: PCI bus numbers covered
- #address-cells: set to <3>
- #size-cells: set to <2>
- device_type: set to "pci"
- ranges: ranges for the PCI memory and I/O regions
Optional properties:
- phys: phandle of the PCIe PHY device
- phy-names: must be "pcie-phy"
- dma-coherent: present if DMA operations are coherent
- dma-ranges: Some PAXB-based root complexes do not have inbound mapping done
by the ASIC after power on reset. In this case, SW is required to configure
the mapping, based on inbound memory regions specified by this property.
- brcm,pcie-ob: Some iProc SoCs do not have the outbound address mapping done
by the ASIC after power on reset. In this case, SW needs to configure it
If the brcm,pcie-ob property is present, the following properties become
effective:
Required:
- brcm,pcie-ob-axi-offset: The offset from the AXI address to the internal
address used by the iProc PCIe core (not the PCIe address)
MSI support (optional):
For older platforms without MSI integrated in the GIC, iProc PCIe core provides
an event queue based MSI support. The iProc MSI uses host memories to store
MSI posted writes in the event queues
On newer iProc platforms, gicv2m or gicv3-its based MSI support should be used
- msi-map: Maps a Requester ID to an MSI controller and associated MSI
sideband data
- msi-parent: Link to the device node of the MSI controller, used when no MSI
sideband data is passed between the iProc PCIe controller and the MSI
controller
Refer to the following binding documents for more detailed description on
the use of 'msi-map' and 'msi-parent':
Documentation/devicetree/bindings/pci/pci-msi.txt
Documentation/devicetree/bindings/interrupt-controller/msi.txt
When the iProc event queue based MSI is used, one needs to define the
following properties in the MSI device node:
- compatible: Must be "brcm,iproc-msi"
- msi-controller: claims itself as an MSI controller
- interrupts: List of interrupt IDs from its parent interrupt device
Optional properties:
- brcm,pcie-msi-inten: Needs to be present for some older iProc platforms that
require the interrupt enable registers to be set explicitly to enable MSI

ARM DynamIQ Shared Unit (DSU) integrates one or more CPU cores with a shared
L3 memory system, control logic and external interfaces to form a multicore
cluster. The PMU enables gathering various statistics on the operation of the
DSU. The PMU provides independent 32-bit counters that can count any of the
supported events, along with a 64-bit cycle counter. The PMU is accessed via
CPU system registers and has no MMIO component.

Drive a GPIO line that can be used to restart the system from a restart
handler.
This binding supports level and edge triggered reset. At driver load
time, the driver will request the given gpio line and install a restart
handler. If the optional properties 'open-source' is not found, the GPIO line
will be driven in the inactive state. Otherwise its not driven until
the restart is initiated.
When the system is restarted, the restart handler will be invoked in
priority order. The gpio is configured as an output, and driven active,
triggering a level triggered reset condition. This will also cause an
inactive->active edge condition, triggering positive edge triggered
reset. After a delay specified by active-delay, the GPIO is set to
inactive, thus causing an active->inactive edge, triggering negative edge
triggered reset. After a delay specified by inactive-delay, the GPIO
is driven active again. After a delay specified by wait-delay, the
restart handler completes allowing other restart handlers to be attempted.
Required properties:
- compatible : should be "gpio-restart".
- gpios : The GPIO to set high/low, see "gpios property" in
Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
low to reset the board set it to "Active Low", otherwise set
gpio to "Active High".
Optional properties:
- open-source : Treat the GPIO as being open source and defer driving
it to when the restart is initiated. If this optional property is not
specified, the GPIO is initialized as an output in its inactive state.
- priority : A priority ranging from 0 to 255 (default 128) according to
the following guidelines:
0: Restart handler of last resort, with limited restart
capabilities
128: Default restart handler; use if no other restart handler is
expected to be available, and/or if restart functionality is
sufficient to restart the entire system
255: Highest priority restart handler, will preempt all other
restart handlers
- active-delay: Delay (default 100) to wait after driving gpio active [ms]
- inactive-delay: Delay (default 100) to wait after driving gpio inactive [ms]
- wait-delay: Delay (default 3000) to wait after completing restart
sequence [ms]
Examples:
gpio-restart {
compatible = "gpio-restart";
gpios = <&gpio 4 0>;
priority = <128>;
active-delay = <100>;
inactive-delay = <100>;
wait-delay = <3000>;

Command DB
---------
Command DB is a database that provides a mapping between resource key and the
resource address for a system resource managed by a remote processor. The data
is stored in a shared memory region and is loaded by the remote processor.
Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for
controlling shared resources. Depending on the board configuration the shared
resource properties may change. These properties are dynamically probed by the
remote processor and made available in the shared memory.
The bindings for Command DB is specified in the reserved-memory section in
devicetree. The devicetree representation of the command DB driver should be:
Properties:
- compatible:
Usage: required
Value type: <string>
Definition: Should be "qcom,cmd-db"
- reg:
Usage: required
Value type: <prop encoded array>
Definition: The register address that points to the actual location of
the Command DB in memory.
Example:
reserved-memory {
[...]
reserved-memory@85fe0000 {
reg = <0x0 0x85fe0000 0x0 0x20000>;
compatible = "qcom,cmd-db";

HWRNG support for the timeriomem_rng driver
Required properties:
- compatible : "timeriomem_rng"
- reg : base address to sample from
- period : wait time in microseconds to use between samples
Optional properties:
- quality : estimated number of bits of true entropy per 1024 bits read from the
rng. Defaults to zero which causes the kernel's default quality to
be used instead. Note that the default quality is usually zero
which disables using this rng to automatically fill the kernel's
entropy pool.
N.B. currently 'reg' must be at least four bytes wide and 32-bit aligned
Example:
hwrng@44 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "timeriomem_rng";
reg = <0x44 0x04>;
