AXP20X and AXP22X PMICs' AC power supply
Required Properties:
- compatible: One of:
"x-powers,axp202-ac-power-supply"
"x-powers,axp221-ac-power-supply"
"x-powers,axp813-ac-power-supply"
This node is a subnode of the axp20x PMIC.
The AXP20X can read the current current and voltage supplied by AC by
reading ADC channels from the AXP20X ADC.
The AXP22X is only able to tell if an AC power supply is present and
usable.
AXP813/AXP803 are able to limit current and supply voltage
Example:
&axp209 {
ac_power_supply: ac-power-supply {
compatible = "x-powers,axp202-ac-power-supply";
};
};

Optional properties:
- monitored-battery: phandle of battery characteristics devicetree node
The charger uses the following battery properties:
+ precharge-current-microamp: maximum charge current during precharge
phase (typically 20% of battery capacity).
+ charge-term-current-microamp: a charge cycle terminates when the
battery voltage is above recharge threshold, and the current is below

Usage: optional
Description: Regulator that is used to control the VBUS voltage direction for
either USB host mode or for charging on the OTG port.
Notes:
- Some circuit boards wire the chip's "OTG" pin high (enabling 500mA default
charge current on USB SDP ports, among other features). To simulate this on
boards that wire the pin to a GPIO, set a gpio-hog.
Example:
bat: battery {

Required properties:
- compatible: Should contain one of the following:
* "ti,bq24250"
* "ti,bq24251"
* "ti,bq24257"
- reg: integer, i2c address of the device.
- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges). Use in
conjunction with "interrupt-parent".
- ti,battery-regulation-voltage: integer, maximum charging voltage in uV.
- ti,charge-current: integer, maximum charging current in uA.
- ti,termination-current: integer, charge will be terminated when current in
constant-voltage phase drops below this value (in uA).
Optional properties:
- pg-gpios: GPIO used for connecting the bq2425x device PG (Power Good) pin.
This pin is not available on all devices however it should be used if
possible as this is the recommended way to obtain the charger's input PG
state. If this pin is not specified a software-based approach for PG
detection is used.
- ti,current-limit: The maximum current to be drawn from the charger's input
(in uA). If this property is not specified, the input limit current is
set automatically using USB D+/D- signal based charger type detection.
If the hardware does not support the D+/D- based detection, a default
of 500,000 is used (=500mA) instead.
- ti,ovp-voltage: Configures the over voltage protection voltage (in uV). If
not specified a default of 6,5000,000 (=6.5V) is used.
- ti,in-dpm-voltage: Configures the threshold input voltage for the dynamic
power path management (in uV). If not specified a default of 4,360,000
(=4.36V) is used.

Analog Devices LT3651 Charger Power Supply bindings: lt3651-charger
Required properties:
- compatible: Should contain one of the following:
* "lltc,ltc3651-charger", (DEPRECATED: Use "lltc,lt3651-charger")
* "lltc,lt3651-charger"
- lltc,acpr-gpios: Connect to ACPR output. See remark below.
Optional properties:
- lltc,fault-gpios: Connect to FAULT output. See remark below.
- lltc,chrg-gpios: Connect to CHRG output. See remark below.
The lt3651 outputs are open-drain type and active low. The driver assumes the
GPIO reports "active" when the output is asserted, so if the pins have been
connected directly, the GPIO flags should be set to active low also.
The driver will attempt to aquire interrupts for all GPIOs to detect changes in
line state. If the system is not capabale of providing interrupts, the driver
cannot report changes and userspace will need to periodically read the sysfs
attributes to detect changes.
Example:
charger: battery-charger {
compatible = "lltc,lt3651-charger";
lltc,acpr-gpios = <&gpio0 68 GPIO_ACTIVE_LOW>;
lltc,fault-gpios = <&gpio0 64 GPIO_ACTIVE_LOW>;

or "lltc,ltc2944" which also indicates the type of I2C chip attached.
- reg: The 7-bit I2C address.
- lltc,resistor-sense: The sense resistor value in milli-ohms. Can be a 32-bit
negative value when the battery has been connected to the wrong end of the
resistor.

of the input power source occurs.
This prevents input voltage drop due to insufficient
current provided by the power source.
Default: 4500000 uV (4.5V)
- richtek,avg-input-current-regulation: integer, input current value in uA drained by the
charger from the power source.
Default: 500000 uA (500mA)
Example:
rt9455@22 {
compatible = "richtek,rt9455";
reg = <0x22>;
interrupt-parent = <&gpio1>;
interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
richtek,output-charge-current = <500000>;
richtek,end-of-charge-percentage = <10>;
richtek,battery-regulation-voltage = <4200000>;
richtek,boost-output-voltage = <5050000>;
richtek,min-input-voltage-regulation = <4500000>;
richtek,avg-input-current-regulation = <500000>;

Binding for sbs-manager
Required properties:
- compatible: "<vendor>,<part-number>", "sbs,sbs-charger" as fallback. The part
number compatible string might be used in order to take care of vendor
specific registers.
- reg: integer, i2c address of the device. Should be <0xa>.
Optional properties:
- gpio-controller: Marks the port as GPIO controller.
See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
- #gpio-cells: Should be <2>. The first cell is the pin number, the second cell
is used to specify optional parameters:
See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
From OS view the device is basically an i2c-mux used to communicate with up to
four smart battery devices at address 0xb. The driver actually implements this
behaviour. So standard i2c-mux nodes can be used to register up to four slave
batteries. Channels will be numerated starting from 1 to 4.
Example:
batman@a {
compatible = "lltc,ltc1760", "sbs,sbs-manager";
reg = <0x0a>;
#address-cells = <1>;
#size-cells = <0>;
gpio-controller;
#gpio-cells = <2>;
i2c@1 {
#address-cells = <1>;
#size-cells = <0>;
reg = <1>;
battery@b {
compatible = "ti,bq2060", "sbs,sbs-battery";
reg = <0x0b>;
sbs,battery-detect-gpios = <&batman 1 1>;
};
};

TI BQ24735 Charge Controller
~~~~~~~~~~
Required properties :
- compatible : "ti,bq24735"
Optional properties :
- interrupts : Specify the interrupt to be used to trigger when the AC
adapter is either plugged in or removed.
- ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter
status. This is a Host GPIO that is configured as an input and connected
to the ACOK pin on the bq24735. Note: for backwards compatibility reasons,
the GPIO must be active on AC adapter absence despite ACOK being active
(high) on AC adapter presence.
- ti,charge-current : Used to control and set the charging current. This value
must be between 128mA and 8.128A with a 64mA step resolution. The POR value
is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
about the ChargeCurrent (0x14h) register.
- ti,charge-voltage : Used to control and set the charging voltage. This value
must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
about the ChargeVoltage (0x15h) register.
- ti,input-current : Used to control and set the charger input current. This
value must be between 128mA and 8.064A with a 128mA step resolution. The
POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
more information about the InputCurrent (0x3fh) register.
- ti,external-control : Indicates that the charger is configured externally
and that the host should not attempt to enable/disable charging or set the
charge voltage/current.
- poll-interval : In case 'interrupts' is not specified, poll AC adapter
presence with this interval (milliseconds).
Example:
bq24735@9 {
compatible = "ti,bq24735";
reg = <0x9>;
ti,ac-detect-gpios = <&gpio 72 0x1>;
}

TWL BCI (Battery Charger Interface)
The battery charger needs to interact with the USB phy in order
to know when charging is permissible, and when there is a connection
or disconnection.
The choice of phy cannot be configured at a hardware level, so there
is no value in explicit configuration in device-tree. Rather
if there is a sibling of the BCI node which is compatible with
"ti,twl4030-usb", then that is used to determine when and how
use USB power for charging.
Required properties:
- compatible:
- "ti,twl4030-bci"
- interrupts: two interrupt lines from the TWL SIH (secondary
interrupt handler) - interrupts 9 and 2.
Optional properties:
- ti,bb-uvolt: microvolts for charging the backup battery.
- ti,bb-uamp: microamps for charging the backup battery.
Examples:
bci {
compatible = "ti,twl4030-bci";
interrupts = <9>, <2>;
ti,bb-uvolt = <3200000>;
ti,bb-uamp = <150>;
