TPS65910 Power Management Integrated Circuit

Required properties:
- compatible: "ti,tps65910" or "ti,tps65911"
- reg: I2C slave address
- interrupts: the interrupt outputs of the controller
- #gpio-cells: number of cells to describe a GPIO, this should be 2.
  The first cell is the GPIO number.
  The second cell is used to specify additional options <unused>.
- gpio-controller: mark the device as a GPIO controller
- #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
  The first cell is the IRQ number.
  The second cell is the flags, encoded as the trigger masks from
  Documentation/devicetree/bindings/interrupts.txt
- regulators: This is the list of child nodes that specify the regulator
  initialization data for defined regulators. Not all regulators for the given
  device need to be present. The definition for each of these nodes is defined
  using the standard binding for regulators found at
  Documentation/devicetree/bindings/regulator/regulator.txt.
  The regulator is matched with the regulator-compatible.

  The valid regulator-compatible values are:
  tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1,
            vaux2, vaux33, vmmc
  tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5,
            ldo6, ldo7, ldo8

Optional properties:
- ti,vmbch-threshold: (tps65911) main battery charged threshold
  comparator. (see VMBCH_VSEL in TPS65910 datasheet)
- ti,vmbch2-threshold: (tps65911) main battery discharged threshold
  comparator. (see VMBCH_VSEL in TPS65910 datasheet)
- ti,en-gpio-sleep: enable sleep control for gpios
  There should be 9 entries here, one for each gpio.
- xxx-supply: Input voltage supply regulator.
  Missing of these properties will be assume as there is no supply regulator
  for that input pins and always powered on.
  The valid input supply properties are:
  tps65910:
	vcc1-supply: VDD1 input.
	vcc2-supply: VDD2 input.
	vcc3-supply: VAUX33 and VMMC input.
	vcc4-supply: VAUX1 and VAUX2 input.
	vcc5-supply: VPLL and VDAC input.
	vcc6-supply: VDIG1 and VDIG2 input.
	vcc7-supply: VRTC input.
	vccio-supply: VIO input.
  tps65911:
	vcc1-supply: VDD1 input.
	vcc2-supply: VDD2 input.
	vcc3-supply: LDO6, LDO7 and LDO8 input.
	vcc4-supply: LDO5 input.
	vcc5-supply: LDO3 and LDO4 input.
	vcc6-supply: LDO1 and LDO2 input.
	vcc7-supply: VRTC input.
	vccio-supply: VIO input.

Regulator Optional properties:
- ti,regulator-ext-sleep-control: enable external sleep
  control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)]
  If this property is not defined, it defaults to 0 (not enabled).
