Display panel driver questions #12

Closed maxfierke closed 2 years ago

maxfierke commented 2 years ago

Trying to figure out more about why the display panel does not come back up after sleep/suspend

@cuu do you have any more information about the CWD686 display and why this particular piece is disabled in the driver?

Also, if there's any schematics or datasheets for the display that you could share, that would be very helpful! More details on the backlight driver would also be helpful too!

This patchset fixes the display suspend/resume issue at the root of my question: https://patchwork.kernel.org/project/linux-rockchip/list/?series=554547 (issues with the Rockchip MIPI DSI driver)
