[PATCH 0/6] drm/bridge: add ycbcr_420_allowed support

[Dmitry Baryshkov]

One of the features that drm_bridge_connector can't handle currently is
setting of the ycbcr_420_allowed flag on the connector. Add the flag to
the drm_bridge struct and propagate it to the drm_connector as AND of
all flags in the bridge chain.

As an example of the conversion, enable the flag on the DW HDMI bridge,
MSM DP bridge, display connector drivers (for DisplayPort and HDMI
outputs) and AUX bridges.
