+TI/National Semiconductor LP3943 GPIO controller
+
+Required properties:
+  - compatible: "ti,lp3943-gpio"
+  - gpio-controller: Marks the device node as a GPIO controller.
+  - #gpio-cells: Should be 2. See gpio.txt in this directory for a
+                 description of the cells format.
+
+Example:
+Simple LED controls with LP3943 GPIO controller
