drm/bridge: synopsys: dw-hdmi: allow ycbcr420 modes for >= 0x200a (f14d3f6c) · Commits · 戴 / test

Now the DW-HDMI Controller supports the HDMI2.0 modes, enable support for these modes in the connector if the platform supports them. We limit these modes to DW-HDMI IP version >= 0x200a which are designed to support HDMI2.0 display modes. Signed-off-by:
