Subject: [PATCH 8/8] drm/meson: Output in YUV444 if sink supports it
Date: Tue, 15 Jan 2019 13:33:15 +0100	[thread overview]
Message-ID: <20190115123315.11069-9-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190115123315.11069-1-narmstrong@baylibre.com>

With the YUV420 handling, we can dynamically setup the HDMI output
pixel format depending on the mode and connector info.
So now, we can output in YUV444, which is the native video pipeline
format, directly to the HDMI Sink if it's supported without
necessarily involving the HDMI Controller CSC.
