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
