Baolin Wang 626b6cd5f5 power: wm831x_power: Support USB charger current limit management
Integrate with the newly added USB charger interface to limit the current
we draw from the USB input based on the input device configuration
identified by the USB stack, allowing us to charge more quickly from high
current inputs without drawing more current than specified from others.

Cirrus Logic/Wolfson Microelectronics wm831x PMICs
System PMICs with a wide range of additional features.
Required properties:
- compatible : One of the following chip-specific strings:
"wlf,wm8310"
"wlf,wm8311"
"wlf,wm8312"
"wlf,wm8320"
"wlf,wm8321"
"wlf,wm8325"
"wlf,wm8326"
- reg : I2C slave address when connected using I2C, chip select number
when using SPI.
- gpio-controller : Indicates this device is a GPIO controller.
- #gpio-cells : Must be 2. The first cell is the pin number and the
second cell is used to specify optional parameters (currently unused).
- interrupts : The interrupt line the IRQ signal for the device is
connected to.
- interrupt-parent : The parent interrupt controller.
- interrupt-controller : wm831x devices contain interrupt controllers and
may provide interrupt services to other devices.
- #interrupt-cells: Must be 2. The first cell is the IRQ number, and the
second cell is the flags, encoded as the trigger masks from
../interrupt-controller/interrupts.txt
Optional sub-nodes:
- phys : Contains a phandle to the USB PHY.
- regulators : Contains sub-nodes for each of the regulators supplied by
the device. The regulators are bound using their names listed below:
dcdc1 : DCDC1
dcdc2 : DCDC2
dcdc3 : DCDC3
dcdc4 : DCDC3
isink1 : ISINK1
isink2 : ISINK2
ldo1 : LDO1
ldo2 : LDO2
ldo3 : LDO3
ldo4 : LDO4
ldo5 : LDO5
ldo7 : LDO7
ldo11 : LDO11
The bindings details of each regulator can be found in:
../regulator/regulator.txt
Example:
wm8310: pmic@36 {
compatible = "wlf,wm8310";
reg = <0x36>;
gpio-controller;
#gpio-cells = <2>;
interrupts = <347>;
interrupt-parent = <&gic>;
interrupt-controller;
#interrupt-cells = <2>;
regulators {
dcdc1: dcdc1 {
regulator-name = "DCDC1";
regulator-min-microvolt = <600000>;
regulator-max-microvolt = <600000>;
};
ldo1: ldo1 {
regulator-name = "LDO1";
regulator-min-microvolt = <1700000>;
regulator-max-microvolt = <1700000>;
};
};
};
