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.
