1 TI/National Semiconductor LP3943 GPIO controller
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.
9 Example:
10 Simple LED controls with LP3943 GPIO controller
