* 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.
Example:
&i2c1 {
...

#address-cells = <1>;
#size-cells = <0>;
compatible = "sgmicro,gsm3784";
reg = <0x30>;
rockchip,camera-module-index = <0>;
rockchip,camera-module-facing = "back";
enable-gpio = <&gpio2 RK_PB4 GPIO_ACTIVE_HIGH>;
strobe-gpio = <&gpio1 RK_PA3 GPIO_ACTIVE_HIGH>;
status = "okay";
sgm3784_led0: led@0 {
reg = <0x0>;
led-max-microamp = <299200>;
flash-max-microamp = <1122000>;
flash-max-timeout-us = <1600000>;
};
sgm3784_led1: led@1 {
reg = <0x1>;
led-max-microamp = <299200>;
flash-max-microamp = <1122000>;
flash-max-timeout-us = <1600000>;
