Subject: [PATCH] drm/meson: Output in YUV444 if sink supports it
|
|
|
|
With the YUV420 handling, we can no dynamically setup the HDMI output
|
|
pixel format depending on the mode and connector info.
|
|
So now, we can output in YUV444, which is the native video pipeline
|
|
format, directly the the HDMI Sink it it's supported, without
|
|
involving the HDMI Controller CSC.
