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
- led-sources : List of enabled channels from 0 to 5.
See Documentation/devicetree/bindings/leds/common.txt
- 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,short-detection-threshold-volt
: It should be one of 4, 5, 6 and 7V.
- skyworks,current-limit-mA
: It should be 2300mA or 2750mA.
Example:
backlight {
compatible = "skyworks,sky81452-backlight";
name = "pwm-backlight";
led-sources = <0 1 2 5>;
skyworks,ignore-pwm;
skyworks,phase-shift;
skyworks,current-limit-mA = <2300>;
};
