[PATCH 0/4 resend] Add ASoC support for AMD Stoney APUs

[Alex Deucher]

This patch set updates the AMD GPU and Audio CoProcessor (ACP)
audio drivers and the designware i2s driver for Stoney (ST).
ST is an APU similar to Carrizo (CZ) which already has ACP audio
support.  The i2s controller and ACP audio DMA engine are part of
the GPU and both need updating so I would like to upstream the
whole patch set via one tree if possible.

I just sent a pull request for the pre-requisite patches which are
available here:
https://cgit.freedesktop.org/~agd5f/linux/log/?h=linus-4.14-rc4-acp-prereq

This is a resend of just the non pre-requisite audio patches at Mark's request.

Thanks!

Alex

  completeness since it's required for this patch set and it's not yet
