Subject: [PATCH 5/8] media: dt-bindings: media: Add Allwinner A83T Rotate driver
Date: Sat, 25 Jan 2020 00:20:11 +0100	[thread overview]
Message-ID: <20200124232014.574989-6-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20200124232014.574989-1-jernej.skrabec@siol.net>

Some Allwinner SoCs like A83T and A64 contain rotate core which can
rotate and flip images.

Add a binding for it.
