    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.
   17 
   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         };
