Subject: [PATCH 0/4] Allwinner D1 video engine support

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.


Samuel Holland (4):
  media: dt-bindings: cedrus: Allow power domain references
  media: dt-bindings: cedrus: Make allwinner,sram optional
  media: cedrus: Make SRAM section claiming optional
  riscv: dts: allwinner: d1: Add video engine node
