I was just wondering if the following would be an acceptable way to turn
off an lcd backlight when the pwm-backlight driver is set to level 0.
The LCD backlight is 'powered' by the gpio.
leds {
compatible = "gpio-leds";
backlight {
label = "lcd-power";
gpios = <&gpio 0 0 0>; /* bank pin active_low */
linux,default-trigger = "backlight";
default-state = "on";
};
};
The method has been tested by an end-user and confirmed as working - I
just wanted to check whether it is the 'accepted' way of doing it.
