+SKY81452-backlight bindings
+
+Required properties:
+- compatible : Must be "skyworks,sky81452-backlight"
+
+Optional properties:
+- name : Name of backlight device. Default is 'lcd-backlight'.
+- gpios : GPIO to use to EN pin.
+ See Documentation/devicetree/bindings/gpio/gpio.txt
+- skyworks,en-channels : Enable mask for current sink channel 1 to 6.
+- skyworks,ignore-pwm : Ignore both PWM input
+- skyworks,dpwm-mode : Enable DPWM dimming mode, otherwise Analog dimming.
+- skyworks,phase-shift : Enable phase shift mode
+- skyworks,ovp-level : Over-voltage protection level.
+ Should be between 14 or 28V.
+- skyworks,short-detection-threshold : It should be one of 4, 5, 6 and 7V.
+- skyworks,current-limit : It should be 2300mA or 2750mA.
+
+Example:
+
+ backlight {
+ compatible = "skyworks,sky81452-backlight";
+ name = "pwm-backlight";
+ skyworks,en-channels = <0x3f>;
+ skyworks,ignore-pwm;
+ skyworks,phase-shift;
+ skyworks,ovp-level = <20>;
+ skyworks,current-limit = <2300>;
+ };
