Hi Maxime,

This series adds support for the PWM controlled backlight on the
A23/A33 Q8 tablets. The A23/A33 SoCs have the same PWM controller
as the A20, and the tablets use it to dim the LCD backlight.

The patches are pretty self-explaining.

Hans, could you test this on your TZX 723Q4? It's FEX file uses
a lower PWM frequency.


Regards
ChenYu
