+Palmas GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "ti,palams-gpio" for palma series of the GPIO controller
+ - "ti,tps80036-gpio" for Palma series device TPS80036.
+ - "ti,tps65913-gpio" for palma series device TPS65913.
+ - "ti,tps65914-gpio" for palma series device TPS65914.
+- #gpio-cells : Should be two.
+ - first cell is the gpio pin number
+ - second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+- gpio-controller : Marks the device node as a GPIO controller.
+
+Note: This gpio node will be sub node of palmas node.
+
+Example:
+ palmas: tps65913@58 {
+ :::::::::::
+ palmas_gpio: palmas_gpio {
+ compatible = "ti,palmas-gpio";
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+ :::::::::::
+ };
