Hi All,

now that the sun4i-spdif driver has made it into linux-next then this patch
series completes what is needed to have SPDIF working on both A10 and A20
devices.

Enjoy,
CK

Changes since v1:
- Added defines to the dma properties and changed reg length to cover the entire
  spdif memory area.

If you're not going to use these pins, please don't add them yet.

In order to avoid bloating the DT uselessly, we try to not add unused nodes.

Thanks!

Sorry, I missed that earlier, but please make separate patches for
those two DTS.

It also applies for the other patches.
