[PATCH 0/3] Add ASoC support for AMD APUs [v2]

[Alex Deucher <alexdeucher@gmail.com>]

This patch set implements support for i2s audio and new AMD GPUs.
The i2s codec is fed by a DMA engine on the GPU.  To handle this
we create an mfd cell which we can hang the i2s codec on.  Because
of this, this patch set covers two subsystems: drm and alsa.  The
drm patches add support for the ACP hw block which provides the DMA
engine for the i2s codec.  The alsa patches add the ASoC driver for
the i2s codec.  Since the alsa changes depend on the drm changes in
this patch set as well as some other drm changes queued for 4.3, I'd
like to take the alsa patches in via the drm tree.

V2 changes:
- Use the MFD subsystem rather than adding our own bus
- Squash all sub-feature patches together
- fix comments mentioned in previous review

There was a question about the code and the module licensing.
IANAL, but this follows the same pattern that most if not all
drm drivers use.

There was also a comment about the patch changelog.  I think this
is more of a subsystem preference kind of thing.  Generally in the
drm we include the patch changelog and versions in the commit
messages so we have a history of the patch if we need to reference
it in the future.  If you have a strong preference for the audio
patch, we can drop that.

Patch 1 adds the register headers for the ACP block which is a
pretty big patch so I've excluded it from email.  The entire patch
set can be viewed here:

Thanks,
