   1 MAX77650 ultra low-power PMIC from Maxim Integrated.
   2
   3 Required properties:
   4 -------------------
   5 - compatible:           Must be "maxim,max77650"
   6 - reg:                  I2C device address.
   7 - interrupts:           The interrupt on the parent the controller is
   8                         connected to.
   9 - interrupt-controller: Marks the device node as an interrupt controller.
  10 - #interrupt-cells:     Must be <2>.
  11
  12 - gpio-controller:      Marks the device node as a gpio controller.
  13 - #gpio-cells:          Must be <2>. The first cell is the pin number and
  14                         the second cell is used to specify the gpio active
  15                         state.
  16
  17 Optional properties:
  18 --------------------
  19 gpio-line-names:        Single string containing the name of the GPIO line.
  20
  21 The GPIO-controller module is represented as part of the top-level PMIC
  22 node. The device exposes a single GPIO line.

  24 For device-tree bindings of other sub-modules (regulator, power supply,
  25 LEDs and onkey) refer to the binding documents under the respective
  26 sub-system directories.

  28 For more details on GPIO bindings, please refer to the generic GPIO DT
  29 binding document <devicetree/bindings/gpio/gpio.txt>.

  32 --------
  33
  34         pmic@48 {
  35                 compatible = "maxim,max77650";
  36                 reg = <0x48>;
  37
  38                 interrupt-controller;
  39                 interrupt-parent = <&gpio2>;
  40                 #interrupt-cells = <2>;
  41                 interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
  42
  43                 gpio-controller;
  44                 #gpio-cells = <2>;
  45                 gpio-line-names = "max77650-charger";
  46         };
