Subject: [PATCH] drm/vc4: Calculate bpc based on max_requested_bpc
|
||
|
|
|
||
|
|
This aligns vc4 with Intel, AMD and Synopsis drivers and fixes max bpc
|
||
|
|
connector property not working as expected on monitors with YCbCr 4:2:2
|
||
|
|
support but not deep color support.
|
||
|
|
|
||
|
|
max_bpc in connector state is clamped at max_bpc from display info and
|
||
|
|
the latter only takes deep color modes into account so it will always
|
||
|
|
be 8, even if the display can do 4:2:2 12-bit output.
