Subject: [PATCH 07/10] drm/sun4i: Add support for D1 mixers
Date: Sun, 10 Apr 2022 23:34:19 -0500 [thread overview]
Message-ID: <20220411043423.37333-8-samuel@sholland.org> (raw)
In-Reply-To: <20220411043423.37333-1-samuel@sholland.org>
D1 has a display engine with the usual pair of mixers, albeit with
relatively few layers. In fact, D1 appears to be the first SoC to have
a mixer without any UI layers. Add support for these new variants.
