Subject: [PATCH] drm/panel: waveshare: Fix up timings for 10.1" panel
|
||
|
|
|
||
|
|
The 10.1" panel doesn't work with the timings defined. vc4
|
||
|
|
will always have been fixing up the timing due to the limited
|
||
|
|
integer divider, so compute the fixed up mode and use it
|
||
|
|
directly.
