Subject: [PATCH 3/3] drm/sun4i: Add support for BT2020 to DE3
Date: Sun, 10 Jan 2021 21:19:47 +0100 [thread overview]
Message-ID: <20210110201947.3611649-4-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20210110201947.3611649-1-jernej.skrabec@siol.net>
DE3 supports 10-bit formats, so it's only naturally to also support
BT2020 encoding.
Add support for it.
