-Subject: [PATCH] drm/vc4: drop unnecessary and harmful HDMI RGB format check
-
-RGB is a mandatory format for all DVI and HDMI monitors so there's
-no need to check for presence of the DRM_COLOR_FORMAT_RGB444 bit in
-color_formats.
-
-More importantly this checks breaks working around EDID issues with
-eg video=HDMI-A-1:1024x768D or drm.edid_firmware=edid/1024x768.bin
-as the RGB444 bit is only set when a valid EDID with digital bit set in
-the input byte is present - which isn't the case when no EDID can be
-read from the display device at all or with the in-built kernel EDIDs,
-which mimic analog (VGA) displays without the digital bit set.
-
-So drop the check, if we output video on the HDMI connector we can
-assume that the display can accept 8bit RGB.
