* AW36518 flash driver support
|
|
|
|
Required Properties:
|
|
- compatible: Must contain "awinic,aw36518"
|
|
- reg: I2C slave address
|
|
- enable-gpios: Specifier of the GPIO connected to strobe/torch EN pin
|
|
this pin is for hardware flash/torch mode, if not, will using i2c control.
|
|
- tx-gpio: Specifier of the GPIO connected to TX pin
|
|
this pin is synchronization input for RF power Amplifier Pulse Eventr;
|
|
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 {
|
|
...
|
|
aw36518: aw36518@63 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "awinic,aw36518";

|
status = "okay";
|
|
reg = <0x63>;
|
|
rockchip,camera-module-index = <0>;
|
|
rockchip,camera-module-facing = "back";

|
enable-gpio = <&gpio3 RK_PC3 GPIO_ACTIVE_HIGH>;
|
|
tx-gpio = <&gpio3 RK_PC2 GPIO_ACTIVE_HIGH>;
|
