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. | |
8 | ||
9 | Example: | |
10 | Simple LED controls with LP3943 GPIO controller | |
