   1 TI/National Semiconductor LP3943 GPIO controller
   2
   3 Required properties:
   4   - compatible: "ti,lp3943-gpio"
   5   - gpio-controller: Marks the device node as a GPIO controller.
   6   - #gpio-cells: Should be 2. See gpio.txt in this directory for a
   7                  description of the cells format.
