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

|
|
|
|
gpioex: gpio {
|
|
compatible = "ti,lp3943-gpio";
|
|

|
|
#gpio-cells = <2>;
|
|
};
|
