Marvell Berlin SoC Family Device Tree Bindings
---------------------------------------------------------------
Work in progress statement:
Device tree files and bindings applying to Marvell Berlin SoCs and boards are
considered "unstable". Any Marvell Berlin device tree binding may change at any
time. Be sure to use a device tree binary and a kernel image generated from the
same source tree.
Please refer to Documentation/devicetree/bindings/ABI.txt for a definition of a
stable binding/ABI.

......@@ -63,90 +74,23 @@ Marvell Berlin SoCs have a system control register set providing several
individual registers dealing with pinmux, padmux, and reset.
Required properties:
- compatible: should be one of
"marvell,berlin2-system-ctrl" for BG2
"marvell,berlin2cd-system-ctrl" for BG2CD
"marvell,berlin2q-system-ctrl" for BG2Q
- compatible:
* the first and second values must be:
"simple-mfd", "syscon"
- reg: address and length of the system control register set
* Clock provider binding
As clock related registers are spread among the chip control registers, the
chip control node also provides the clocks. Marvell Berlin2 (BG2, BG2CD, BG2Q)
SoCs share the same IP for PLLs and clocks, with some minor differences in
features and register layout.
Required properties:
- #clock-cells: shall be set to 1
- clocks: clock specifiers referencing the core clock input clocks
- clock-names: array of strings describing the input clock specifiers above.
Allowed clock-names for the reference clocks are
"refclk" for the SoCs osciallator input on all SoCs,
and SoC-specific input clocks for
BG2/BG2CD: "video_ext0" for the external video clock input
Clocks provided by core clocks shall be referenced by a clock specifier
indexing one of the provided clocks. Refer to dt-bindings/clock/berlin<soc>.h
for the corresponding index mapping.
* Pin controller binding
Pin control registers are part of both register sets, chip control and system
control. The pins controlled are organized in groups, so no actual pin
information is needed.
A pin-controller node should contain subnodes representing the pin group
configurations, one per function. Each subnode has the group name and the muxing
function used.
Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called
a 'function' in the pin-controller subsystem.
Required subnode-properties:
- groups: a list of strings describing the group names.
- function: a string describing the function used to mux the groups.
* Reset controller binding
A reset controller is part of the chip control registers set. The chip control
node also provides the reset. The register set is not at the same offset between
Berlin SoCs.
Required property:
- #reset-cells: must be set to 2
Example:
chip: chip-control@ea0000 {
compatible = "marvell,berlin2-chip-ctrl";
#clock-cells = <1>;
#reset-cells = <2>;
compatible = "simple-mfd", "syscon";
reg = <0xea0000 0x400>;
clocks = <&refclk>, <&externaldev 0>;
clock-names = "refclk", "video_ext0";
spi1_pmux: spi1-pmux {
groups = "G0";
function = "spi1";
};
/* sub-device nodes */
};
sysctrl: system-controller@d000 {
compatible = "marvell,berlin2-system-ctrl";
compatible = "simple-mfd", "syscon";
reg = <0xd000 0x100>;
uart0_pmux: uart0-pmux {
groups = "GSM4";
function = "uart0";
};
uart1_pmux: uart1-pmux {
groups = "GSM5";
function = "uart1";
};
uart2_pmux: uart2-pmux {
groups = "GSM3";
function = "uart2";
};
/* sub-device nodes */
};
Device Tree Clock bindings for Marvell Berlin
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Clock related registers are spread among the chip control registers. Berlin
clock node should be a sub-node of the chip controller node. Marvell Berlin2
(BG2, BG2CD, BG2Q) SoCs share the same IP for PLLs and clocks, with some
minor differences in features and register layout.
Required properties:
- compatible: must be "marvell,berlin2-clk" or "marvell,berlin2q-clk"
- #clock-cells: must be 1
- clocks: must be the input parent clock phandle
- clock-names: name of the input parent clock
Allowed clock-names for the reference clocks are
"refclk" for the SoCs oscillator input on all SoCs,
and SoC-specific input clocks for
BG2/BG2CD: "video_ext0" for the external video clock input
Example:
chip_clk: clock {
compatible = "marvell,berlin2q-clk";
#clock-cells = <1>;
clocks = <&refclk>;
clock-names = "refclk";
};
* Pin-controller driver for the Marvell Berlin SoCs
Pin control registers are part of both chip controller and system
controller register sets. Pin controller nodes should be a sub-node of
either the chip controller or system controller node. The pins
controlled are organized in groups, so no actual pin information is
needed.
A pin-controller node should contain subnodes representing the pin group
configurations, one per function. Each subnode has the group name and
the muxing function used.
Be aware the Marvell Berlin datasheets use the keyword 'mode' for what
is called a 'function' in the pin-controller subsystem.
Required properties:
- compatible: should be one of:
"marvell,berlin2-soc-pinctrl",
"marvell,berlin2-system-pinctrl",
"marvell,berlin2cd-soc-pinctrl",
"marvell,berlin2cd-system-pinctrl",
"marvell,berlin2q-soc-pinctrl",
"marvell,berlin2q-system-pinctrl"
Required subnode-properties:
- groups: a list of strings describing the group names.
- function: a string describing the function used to mux the groups.
Example:
sys_pinctrl: pin-controller {
compatible = "marvell,berlin2q-system-pinctrl";
uart0_pmux: uart0-pmux {
groups = "GSM12";
function = "uart0";
};
};
&uart0 {
pinctrl-0 = <&uart0_pmux>;
pinctrl-names = "default";
};
Marvell Berlin reset controller
===============================
Please also refer to reset.txt in this directory for common reset
controller binding usage.
The reset controller node must be a sub-node of the chip controller
node on Berlin SoCs.
Required properties:
- compatible: should be "marvell,berlin2-reset"
- #reset-cells: must be set to 2
Example:
chip_rst: reset {
compatible = "marvell,berlin2-reset";
#reset-cells = <2>;
};
&usb_phy0 {
resets = <&chip_rst 0x104 12>;
};
