* SGM3784 dual flash driver support
|
|
Required Properties:
|
- compatible: Must contain "sgmicro,gsm3784"
|
- reg: I2C slave address
|
- enable-gpios: Specifier of the GPIO connected to EN pin
|
- strobe-gpio: Specifier of the GPIO connected to STROBE pin
|
- torch-gpio: Specifier of the GPIO connected to GPIO pin,
|
this pin is for torch mode, if not, will using assist mode.
|
|
|
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
|
|
Special properties:
|
- rockchip,camera-module-index : indicate which camera the flash belongs to.
|
- rockchip,camera-module-facing : indicate the camera facing.
|
|
