From: Florent Revest <florent.rev...@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.
