* Texas Instruments - lp8860 4-Channel LED Driver
The LP8860-Q1 is an high-efficiency LED
driver with boost controller. It has 4 high-precision
current sinks that can be controlled by a PWM input
signal, a SPI/I2C master, or both.
Required properties:
- compatible :
"ti,lp8860"
- reg : I2C slave address
- #address-cells : 1
- #size-cells : 0
Optional properties:
- enable-gpios : gpio pin to enable (active high)/disable the device.
- vled-supply : LED supply
Required child properties:
- reg : 0
Optional child properties:
- function : see Documentation/devicetree/bindings/leds/common.txt
- color : see Documentation/devicetree/bindings/leds/common.txt
- label : see Documentation/devicetree/bindings/leds/common.txt (deprecated)
- linux,default-trigger :
see Documentation/devicetree/bindings/leds/common.txt
Example:
#include <dt-bindings/leds/common.h>
led-controller@2d {
compatible = "ti,lp8860";
#address-cells = <1>;
#size-cells = <0>;
reg = <0x2d>;
enable-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
vled-supply = <&vbatt>;
led@0 {
reg = <0>;
function = LED_FUNCTION_BACKLIGHT;
color = <LED_COLOR_ID_WHITE>;
linux,default-trigger = "backlight";
};
}
