Kernel-4.18.0-80.el8_wm831x

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>;
    };
};
