    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.
