Subject: [PATCH] drm/vc4: hdmi: Fix no video output on DVI monitors
|
|
|
|
The drm edid parser doesn't signal RGB support on DVI monitors
|
|
with old edid versions, leading to 8-bit RGB mode being rejected
|
|
and no video on DVI monitors.
|
|
|
|
As 8-bit RGB is mandatory on HDMI and DVI monitors anyways we can
|
|
simply drop the RGB format check, aligning vc4 with other drivers.
