Subject: [PATCH 1/5] drm/bridge: dw-hdmi: allow ycbcr420 modes for >= 0x200a
Date: Mon, 20 May 2019 15:37:49 +0200
Message-ID: <20190520133753.23871-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190520133753.23871-1-narmstrong@baylibre.com>

Now the DW-HDMI Controller supports the HDMI2.0 modes, enable support
for these modes in the connector if the platform supports them.
We limit these modes to DW-HDMI IP version >= 0x200a which
are designed to support HDMI2.0 display modes.
