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 valid names for regulators 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.

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).

Example:

		interrupts = < 0 118 0x04 >;

		#gpio-cells = <2>;
		gpio-controller;

		#interrupt-cells = <2>;
		interrupt-controller;

		ti,vmbch-threshold = 0;
		ti,vmbch2-threshold = 0;

		ti,en-gpio-sleep = <0 0 1 0 0 0 0 0 0>;
