* Texas Instruments - LM3692x Highly Efficient White LED Driver
The LM3692x is an ultra-compact, highly efficient,
white-LED driver designed for LCD display backlighting.
The main difference between the LM36922 and LM36923 is the number of
LED strings it supports. The LM36922 supports two strings while the LM36923
supports three strings.
Required properties:
- compatible:
"ti,lm36922"
"ti,lm36923"
- reg : I2C slave address
- #address-cells : 1
- #size-cells : 0
Optional properties:
- enable-gpios : gpio pin to enable/disable the device.
- vled-supply : LED supply
Required child properties:
- reg : 0
Optional child properties:
- label : see Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger :
see Documentation/devicetree/bindings/leds/common.txt
Example:
led-controller@36 {
compatible = "ti,lm3692x";
reg = <0x36>;
#address-cells = <1>;
#size-cells = <0>;
enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
vled-supply = <&vbatt>;
led@0 {
reg = <0>;
label = "white:backlight_cluster";
linux,default-trigger = "backlight";
};
}
