Subject: [PATCH 4/5] drm/meson: Add YUV420 output support
This patch adds support for the YUV420 output from the Amlogic Meson SoCs
Video Processing Unit to the HDMI Controller.
The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.
In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.
This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ration with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.
This patch adds the TMDS PHY clock value in all the video clock setup
in order to better support these specific uses cases and switch
to the Common Clock framework for clocks handling in the future.
When 420 is needed, it calls drm_bridge_format_set() for notify the
bridge the input format has changed to YUV420.
