1	TPS65910 Power Management Integrated Circuit
2	
3	Required properties:
4	- compatible: "ti,tps65910" or "ti,tps65911"
5	- reg: I2C slave address
6	- interrupts: the interrupt outputs of the controller
7	- #gpio-cells: number of cells to describe a GPIO, this should be 2.
8	  The first cell is the GPIO number.
9	  The second cell is used to specify additional options <unused>.
10	- gpio-controller: mark the device as a GPIO controller
11	- #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
12	  The first cell is the IRQ number.
13	  The second cell is the flags, encoded as the trigger masks from
14	  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
15	- regulators: This is the list of child nodes that specify the regulator
16	  initialization data for defined regulators. Not all regulators for the given
17	  device need to be present. The definition for each of these nodes is defined
18	  using the standard binding for regulators found at
19	  Documentation/devicetree/bindings/regulator/regulator.txt.
20	  The regulator is matched with the regulator-compatible.
21	
22	  The valid regulator-compatible values are:
23	  tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1,
24	            vaux2, vaux33, vmmc, vbb
25	  tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5,
26	            ldo6, ldo7, ldo8
27	
28	- xxx-supply: Input voltage supply regulator.
29	  These entries are require if regulators are enabled for a device. Missing of these
30	  properties can cause the regulator registration fails.
31	  If some of input supply is powered through battery or always-on supply then
32	  also it is require to have these parameters with proper node handle of always
33	  on power supply.
34	  tps65910:
35		vcc1-supply: VDD1 input.
36		vcc2-supply: VDD2 input.
37		vcc3-supply: VAUX33 and VMMC input.
38		vcc4-supply: VAUX1 and VAUX2 input.
39		vcc5-supply: VPLL and VDAC input.
40		vcc6-supply: VDIG1 and VDIG2 input.
41		vcc7-supply: VRTC and VBB input.
42		vccio-supply: VIO input.
43	  tps65911:
44		vcc1-supply: VDD1 input.
45		vcc2-supply: VDD2 input.
46		vcc3-supply: LDO6, LDO7 and LDO8 input.
47		vcc4-supply: LDO5 input.
48		vcc5-supply: LDO3 and LDO4 input.
49		vcc6-supply: LDO1 and LDO2 input.
50		vcc7-supply: VRTC input.
51		vccio-supply: VIO input.
52	
53	Optional properties:
54	- ti,vmbch-threshold: (tps65911) main battery charged threshold
55	  comparator. (see VMBCH_VSEL in TPS65910 datasheet)
56	- ti,vmbch2-threshold: (tps65911) main battery discharged threshold
57	  comparator. (see VMBCH_VSEL in TPS65910 datasheet)
58	- ti,en-ck32k-xtal: enable external 32-kHz crystal oscillator (see CK32K_CTRL
59	  in TPS6591X datasheet)
60	- ti,en-gpio-sleep: enable sleep control for gpios
61	  There should be 9 entries here, one for each gpio.
62	- ti,system-power-controller: Telling whether or not this pmic is controlling
63	  the system power.
64	- ti,sleep-enable: Enable SLEEP state.
65	- ti,sleep-keep-therm: Keep thermal monitoring on in sleep state.
66	- ti,sleep-keep-ck32k: Keep the 32KHz clock output on in sleep state.
67	- ti,sleep-keep-hsclk: Keep high speed internal clock on in sleep state.
68	
69	Regulator Optional properties:
70	- ti,regulator-ext-sleep-control: enable external sleep
71	  control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)]
72	  If this property is not defined, it defaults to 0 (not enabled).
