   1 Palmas GPIO controller bindings
   2
   3 Required properties:
   4 - compatible:
   5   - "ti,palams-gpio" for palma series of the GPIO controller
   6   - "ti,tps80036-gpio" for Palma series device TPS80036.
   7   - "ti,tps65913-gpio" for palma series device TPS65913.
   8   - "ti,tps65914-gpio" for palma series device TPS65914.
   9 - #gpio-cells : Should be two.
  10   - first cell is the gpio pin number
  11   - second cell is used to specify the gpio polarity:
  12       0 = active high
  13       1 = active low
  14 - gpio-controller : Marks the device node as a GPIO controller.
  15
  16 Note: This gpio node will be sub node of palmas node.

  18 Example:
  19         palmas: tps65913@58 {
  20                 :::::::::::
  21                 palmas_gpio: palmas_gpio {
  22                         compatible = "ti,palmas-gpio";
  23                         gpio-controller;
  24                         #gpio-cells = <2>;
  25                 };
  26                 :::::::::::
  27         };
