[0/4] Allwinner D1 video engine support

Message

This series finishes adding Cedrus support for Allwinner D1. I had
tested the hardware and documented the compatible string a while back,
but at the time I had a dummy SRAM section in the devicetree. Further
testing shows that there is no switchable SRAM section -- there is no
need for it, I was unable to guess the address, and the usual bits in
the SRAM controller register have no effect on the video engine. So that
needs to be made optional in the binding and driver.

With that done, the node can be added to the devicetree.

Hi Samuel,

What is the status of this series? It seems to be mostly OK, but I did see
a few comments suggesting improvements.

Does this series depend on your PPU work? That was not clear.

I do think there were enough small comments to warrant a v2, unless you disagree?

Regards,

	Hans

The first three patches do not, but the actual DT node does, for
completeness.

I agree, and plan to send a v2 with the binding/driver changes made
compatible-specific.
