Subject: [PATCH 0/4] ARM: dts: sun8i: Add pwm-backlight device for A23/A33 Q8 format tablets
Date: Fri, 18 Sep 2015 15:35:35 +0800 [thread overview]
Message-ID: <1442561739-6824-1-git-send-email-wens@csie.org> (raw)
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
