1 Cirrus Logic/Wolfson Microelectronics wm831x PMICs
2
3 System PMICs with a wide range of additional features.
4
5 Required properties:
6
7 - compatible : One of the following chip-specific strings:
8 "wlf,wm8310"
9 "wlf,wm8311"
10 "wlf,wm8312"
11 "wlf,wm8320"
12 "wlf,wm8321"
13 "wlf,wm8325"
14 "wlf,wm8326"
15
16 - reg : I2C slave address when connected using I2C, chip select number
17 when using SPI.
18
19 - gpio-controller : Indicates this device is a GPIO controller.
20 - #gpio-cells : Must be 2. The first cell is the pin number and the
21 second cell is used to specify optional parameters (currently unused).
22
23 - interrupts : The interrupt line the IRQ signal for the device is
24 connected to.
25
26 - interrupt-controller : wm831x devices contain interrupt controllers and
27 may provide interrupt services to other devices.
28 - #interrupt-cells: Must be 2. The first cell is the IRQ number, and the
29 second cell is the flags, encoded as the trigger masks from
30 ../interrupt-controller/interrupts.txt
31
32 Optional sub-nodes:
33 - phys : Contains a phandle to the USB PHY.
34 - regulators : Contains sub-nodes for each of the regulators supplied by
35 the device. The regulators are bound using their names listed below:
36
37 dcdc1 : DCDC1
38 dcdc2 : DCDC2
39 dcdc3 : DCDC3
40 dcdc4 : DCDC3
41 isink1 : ISINK1
42 isink2 : ISINK2
43 ldo1 : LDO1
44 ldo2 : LDO2
45 ldo3 : LDO3
46 ldo4 : LDO4
47 ldo5 : LDO5
48 ldo7 : LDO7
49 ldo11 : LDO11
50
51 The bindings details of each regulator can be found in:
52 ../regulator/regulator.txt

54 Example:
55
56 wm8310: pmic@36 {
57 compatible = "wlf,wm8310";
58 reg = <0x36>;
59
60 gpio-controller;

62
63 interrupts = <347>;
64 interrupt-parent = <&gic>;
65
66 interrupt-controller;
67 #interrupt-cells = <2>;
68
69 regulators {
70 dcdc1: dcdc1 {
71 regulator-name = "DCDC1";
72 regulator-min-microvolt = <600000>;
73 regulator-max-microvolt = <600000>;
74 };
75 ldo1: ldo1 {
76 regulator-name = "LDO1";
77 regulator-min-microvolt = <1700000>;
78 regulator-max-microvolt = <1700000>;
79 };
80 };
81 };
