[PATCH 0/6] drm/display: hdmi: add drm_hdmi_connector_mode_valid()

[Dmitry Baryshkov]

Several HDMI drivers have common code pice in the .mode_valid function
that validates RGB / 8bpc rate using the TMDS char rate callbacks.

Move this code piece to the common helper and remove the need to perform
this check manually. In case of DRM_BRIDGE_OP_HDMI bridges the check can
be dropped in favour of performing it in drm_bridge_connector.
