Subject: [PATCH v2 5/5] gpu/drm: mediatek: hdmi: add MT8167 configuration
Date: Mon, 12 Apr 2021 11:39:28 +0200	[thread overview]
Message-ID: <20210412093928.3321194-6-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210412093928.3321194-1-narmstrong@baylibre.com>

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.
