The device is controlled through enable gpio pin.
|
gpio asserted high, enable flash strobe.
|
|
Required properties:
|
|
- compatible : Must be "led,rgb13h".
|
- enable-gpios : Must be device tree identifier of the flash device enable pin.
|
|
A discrete LED element connected to the device must be represented by a child
|
node - see Documentation/devicetree/bindings/leds/common.txt.
|
|
Required properties of the LED child node:
|
- led-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
|
- flash-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
|
- flash-max-timeout-us : see Documentation/devicetree/bindings/leds/common.txt
|
|
Optional properties of the LED child node:
|
- label : see Documentation/devicetree/bindings/leds/common.txt
|
|
Special properties:
|
- rockchip,camera-module-index : indicate which camera the flash belongs to.
|
- rockchip,camera-module-facing : indicate the camera facing.
