Subject: [PATCH] drm/panel: simple: Alter the timing for the Pi 7" DSI display
|
|
|
|
vc4 has always fixed up the timing, so the values defined have
|
|
never actually appeared on the wire.
|
|
The display appears to want a slightly longer HFP, so extend
|
|
the timings and recompute the clock to give the same frame rate.
