+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:
+
+ pmu: tps65910@d2 {
+ compatible = "ti,tps65910";
+ reg = <0xd2>;
+ interrupt-parent = <&intc>;
+ 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>;
