[PATCH v3 5/5] gpu/drm: mediatek: hdmi: add MT8167 configuration

From: Neil Armstrong
Date: Mon Apr 19 2021 - 03:33:48 EST


The MT8167 SoC have a hard limit on the maximal supported HDMI TMDS clock,
and is not validated and supported for HDMI modes out of HDMI CEA modes,
so add a configuration entry linked to the MT8167 compatible.
