Subject[PATCH 7/9] ARM: dts: sun5i: Use video-engine node
Date
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.
