Subject: [PATCH v3 3/5] gpu/drm: mediatek: hdmi: add check for CEA modes only
Date: Mon, 19 Apr 2021 09:32:42 +0200 [thread overview]
Message-ID: <20210419073244.2678688-4-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210419073244.2678688-1-narmstrong@baylibre.com>
Some SoCs like the MT8167 are not validated and supported for HDMI modes
out of HDMI CEA modes, so add a configuration boolean to filter out
non-CEA modes.
