[alsa-devel] [PATCH 0/8] Add ASoC support for AMD APUs [v4]

[Alex Deucher]

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 mfd cells which we hang the i2s codec and DMA engine 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

V3 changes:
- Update the designware driver to handle slave mode, amd specific
  features
- Use the designware driver directly for i2s
- Move the DMA handling from the GPU driver into the AMD ASoC
  driver
- Change the license on the ASoC driver to GPL

v4 changes:
- patch "ASoC : dwc : support dw i2s in slave mode" accepted
- Add a _dai_fmt() operation that checks to make sure that the mode
  we're setting corresponds to what we read back from the hardware.
- Split specific quirks into separate patches
- Set the specific quirks that apply to AMD chips in the acp driver

Patch 7 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,
