1	* Dialog DA9055 Power Management Integrated Circuit (PMIC)
2	
3	DA9055 consists of a large and varied group of sub-devices (I2C Only):
4	
5	Device			 Supply Names	 Description
6	------			 ------------	 -----------
7	da9055-gpio		:		: GPIOs
8	da9055-regulator	:		: Regulators
9	da9055-onkey		:		: On key
10	da9055-rtc		:		: RTC
11	da9055-hwmon		:		: ADC
12	da9055-watchdog		:		: Watchdog
13	
14	The CODEC device in DA9055 has a separate, configurable I2C address and so
15	is instantiated separately from the PMIC.
16	
17	For details on accompanying CODEC I2C device, see the following:
18	Documentation/devicetree/bindings/sound/da9055.txt
19	
20	======
21	
22	Required properties:
23	- compatible : Should be "dlg,da9055-pmic"
24	- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
25	- interrupt-parent: Specifies the phandle of the interrupt controller to which
26	  the IRQs from da9055 are delivered to.
27	- interrupts: IRQ line info for da9055 chip.
28	- interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
29	- #interrupt-cells: Should be 1, is the local IRQ number for da9055.
30	
31	Sub-nodes:
32	- regulators : Contain the regulator nodes. The DA9055 regulators are
33	  bound using their names as listed below:
34	
35	    buck1     : regulator BUCK1
36	    buck2     : regulator BUCK2
37	    ldo1      : regulator LDO1
38	    ldo2      : regulator LDO2
39	    ldo3      : regulator LDO3
40	    ldo4      : regulator LDO4
41	    ldo5      : regulator LDO5
42	    ldo6      : regulator LDO6
43	
44	  The bindings details of individual regulator device can be found in:

50		pmic: da9055-pmic@5a {
51			compatible = "dlg,da9055-pmic";
52			reg = <0x5a>;
53			interrupt-parent = <&intc>;
54			interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
55			interrupt-controller;
56			#interrupt-cells = <1>;

58			regulators {
59				buck1: BUCK1 {
60					regulator-min-microvolt = <725000>;
61					regulator-max-microvolt = <2075000>;
62				};
63				buck2: BUCK2 {
64					regulator-min-microvolt = <925000>;
65					regulator-max-microvolt = <2500000>;
66				};
67				ldo1: LDO1 {
68					regulator-min-microvolt = <900000>;
69					regulator-max-microvolt = <3300000>;
70				};
71			};
