1	ACT88xx regulators
2	-------------------
3	
4	Required properties:
5	- compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600"
6	- reg: I2C slave address
7	
8	Optional properties:
9	- system-power-controller: Telling whether or not this pmic is controlling
10	  the system power. See Documentation/devicetree/bindings/power/power-controller.txt .
11	- active-semi,vsel-high: Indicates the VSEL pin is high.
12	  If this property is missing, assume the VSEL pin is low(0).
13	
14	Optional input supply properties:
15	- for act8600:
16	  - vp1-supply: The input supply for DCDC_REG1
17	  - vp2-supply: The input supply for DCDC_REG2
18	  - vp3-supply: The input supply for DCDC_REG3
19	  - inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8
20	  SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies.
21	- for act8846:
22	  - vp1-supply: The input supply for REG1
23	  - vp2-supply: The input supply for REG2
24	  - vp3-supply: The input supply for REG3
25	  - vp4-supply: The input supply for REG4
26	  - inl1-supply: The input supply for REG5, REG6 and REG7
27	  - inl2-supply: The input supply for REG8 and LDO_REG9
28	  - inl3-supply: The input supply for REG10, REG11 and REG12
29	- for act8865:
30	  - vp1-supply: The input supply for DCDC_REG1
31	  - vp2-supply: The input supply for DCDC_REG2
32	  - vp3-supply: The input supply for DCDC_REG3
33	  - inl45-supply: The input supply for LDO_REG1 and LDO_REG2
34	  - inl67-supply: The input supply for LDO_REG3 and LDO_REG4
35	
36	Any standard regulator properties can be used to configure the single regulator.
37	
38	The valid names for regulators are:
39		- for act8846:
40		REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12
41		- for act8865:
42		DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
43		- for act8600:
44		DCDC_REG1, DCDC_REG2, DCDC_REG3, SUDCDC_REG4, LDO_REG5, LDO_REG6, LDO_REG7,
45		LDO_REG8, LDO_REG9, LDO_REG10,
