    +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,regulator-ext-sleep-control: enable external sleep
    + control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)]
    + There should be 13 entries here, one for each regulators for the chip.
    +- ti,en-gpio-sleep: enable sleep control for gpios
    + There should be 9 entries here, one for each gpio.
    +
    +Example:
    +
    + pmu: tps65910@d2 {
    + compatible = "ti,tps65910";
    + reg = <0xd2>;
    + interrupt-parent = <&intc>;
    + interrupts = < 0 118 0x04 >;
