+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.
+
