Cover letter [RFC 0/8] DPCM with simple-card support for Kirkwood

30 June you posted your code to implement DPCM for kirkwood-i2s, making it possible to use both I2S and SPDIF at the same time.

It has taken me a while, but i now have this patch on 3.16-rc6, and i've extended simple-card to support DPCM. I've tested it on a kirkwood based HP T5325, which only makes use of the I2S backend.

Please could you take a look and see if this helps to unblock getting your Cubox support into mainline.

Andrew,

I had quite the same code as yours end 2013, and, if I did not miss something:

- you cannot put Linux specific stuff in the DT:

- the DPCM code does not handle the formats and rates of the back-ends:
