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-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>;
|
};
|
};
|
};
