Subject: [PATCH 6/8] drm/bridge: dw-hdmi: allow ycbcr420 modes for >= 0x200a
Date: Tue, 15 Jan 2019 13:33:13 +0100 [thread overview]
Message-ID: <20190115123315.11069-7-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190115123315.11069-1-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.
