Subject: [PATCH v5 55/80] drm/vc4: hdmi: Add a CSC setup callback
Date: Thu,  3 Sep 2020 10:01:27 +0200	[thread overview]
Message-ID: <5c19bbf10153cb42ca0fb67e08606c8295c17236.1599120059.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.dddc064d8bb83e46744336af67dcb13139e5747d.1599120059.git-series.maxime@cerno.tech>

Similarly to the previous patches, the CSC setup is slightly different in
the BCM2711 than in the previous generations. Let's add a callback for it.
