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>;
};
};
};
