Here, I don't understand, the commit message is too short. Are there 2 brightness controls on magician, or are these 2 different magicians (hardware wise), each having a different backlight control ? Or is it there is a GPIO to light up the screen and a PWM backlight ? I have to understand first. Cheers. -- Robert
