+* 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.
+
