Subject: [PATCH 5/5] drm/meson: Output in YUV444 if sink supports it
|
|
|
|
With the YUV420 handling, we can 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 to the HDMI Sink if it's supported without
|
|
necessarily involving the HDMI Controller CSC.
