Subject: [PATCH 7/9] ARM: dts: sun5i: Use video-engine node
Date:   Fri,  9 Mar 2018 11:14:43 +0100
Message-Id: <20180309101445.16190-5-paul.kocialkowski@bootlin.com>
In-Reply-To: <20180309100933.15922-3-paul.kocialkowski@bootlin.com>
References: <20180309100933.15922-3-paul.kocialkowski@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Florent Revest <florent.revest@free-electrons.com>

Now that we have a driver matching "allwinner,sun4i-a10-video-engine" we
can load it.

The "video-engine" node depends on the new sunxi-ng's CCU clock and
reset bindings. This patch also includes a ve_reserved DMA pool for
videobuf2 buffer allocations in sunxi-cedrus.
