[alsa-devel] [PATCH v4 0/7] ASoC: intel - add skylake PCM driver

[Vinod Koul]

SKL has HDA controller based audio subsystem with DSP and support for I2S,
HDA, PDM links. The hda core code has been moved to sound/hda/ by Takashi
which current HDA drivers use and will also be used by ASoC SKL driver.

The SKL platform driver will load and create the soc_hdac_bus which embeds
the hdac_bus, same for hdac_device (hda codecs) and hdac_stream (pcms) This
is on top of hdac code in Takashi's topic/hda

This patch provides the match function for asoc type hda codecs and let's
them get enumerated by hdac. The second patch in this series adds the
controller specific soc code. Common parts are in hdac core with changes
introduced as part of SKL controller in soc part. Then we add the rest of
controller PCM driver code (still HDA) and last patch breaks the HDA streams
to host and link which will allow insertion of DSP in between these links.

The subsequent series will add IPC driver for SKL (using common IPC
routines), then DSP topology handlers, DSP code with I2S support and then
lastly when DFW is accepted then its handlers.

This patch series adds the hda codec match functions followed by asoc hda
controller routines, then SKL PCM driver and last decouples the controller
for splitting the links

Fixes in v4:
  Updates changelog in patch1 and few other patches
  Address Takashi's comment
  Address Marks comments
