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
&i2c4 {
lp3943@60 {
compatible = "ti,lp3943";
reg = <0x60>;
gpioex: gpio {
compatible = "ti,lp3943-gpio";
gpio-controller;
#gpio-cells = <2>;
};
};
};
leds {
compatible = "gpio-leds";
indicator1 {
label = "indi1";
gpios = <&gpioex 9 GPIO_ACTIVE_LOW>;
};
indicator2 {
label = "indi2";
gpios = <&gpioex 10 GPIO_ACTIVE_LOW>;
default-state = "off";
};
};
