   1 TPS65910 Power Management Integrated Circuit
   2
   3 Required properties:
   4 - compatible: "ti,tps65910" or "ti,tps65911"
   5 - reg: I2C slave address
   6 - interrupts: the interrupt outputs of the controller
   7 - #gpio-cells: number of cells to describe a GPIO, this should be 2.
   8   The first cell is the GPIO number.
   9   The second cell is used to specify additional options <unused>.
  10 - gpio-controller: mark the device as a GPIO controller
  11 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
  12   The first cell is the IRQ number.
  13   The second cell is the flags, encoded as the trigger masks from
  14   Documentation/devicetree/bindings/interrupts.txt
  15 - regulators: This is the list of child nodes that specify the regulator
  16   initialization data for defined regulators. Not all regulators for the given
  17   device need to be present. The definition for each of these nodes is defined
  18   using the standard binding for regulators found at
  19   Documentation/devicetree/bindings/regulator/regulator.txt.
  20   The regulator is matched with the regulator-compatible.
  21
  22   The valid regulator-compatible values are:
  23   tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1,
  24             vaux2, vaux33, vmmc
  25   tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5,
  26             ldo6, ldo7, ldo8
  27
  28 Optional properties:
  29 - ti,vmbch-threshold: (tps65911) main battery charged threshold
  30   comparator. (see VMBCH_VSEL in TPS65910 datasheet)
  31 - ti,vmbch2-threshold: (tps65911) main battery discharged threshold
  32   comparator. (see VMBCH_VSEL in TPS65910 datasheet)
  33 - ti,en-gpio-sleep: enable sleep control for gpios
  34   There should be 9 entries here, one for each gpio.
  35
  36 Regulator Optional properties:
  37 - ti,regulator-ext-sleep-control: enable external sleep
  38   control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)]
  39   If this property is not defined, it defaults to 0 (not enabled).
