+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>;
+               };
+               :::::::::::
+       };
