[PATCH 0/8] ASoC: Intel: avs: PCM code cleanup

[Cezary Rojewski <cezary.rojewski@xxxxxxxxx>]

A set of changes that aims to improve readability of cohesiveness of the
pcm code for the avs-driver.

Start off with a change that synchronizes DAI open/close - DAIs are
started up in ascending order yet their shutdown does not follow the
scheme - it is done in the ascending order too, rather than desceding
one. This patch is a dependency for the next one in line.

To align the HDAudio DAI startup/shutdown with the non-HDAudio
equivalents, relocate the code from component to DAI. The reason above
is a dependency stems from codec driver requirements - HDAudio code
found in sound/pci/hda/ expects substream->runtime->private_data to
point to a valid stream (HOST) pointer.

With the hard part done, the follow up changes update the existing code
to reduce it is complexity - removal of duplicates, renaming of
ambiguous functions and adding new fields to DAI-data object so that the
number of local variables and casts is reduced.

Cezary Rojewski (8):
  ASoC: pcm: Reverse iterate DAIs when shutting them down
  ASoC: Intel: avs: Relocate HDA BE DAI specific operations
  ASoC: Intel: avs: Remove redundancy around DAI shutdown
  ASoC: Intel: avs: Store pointer to adev in DAI dma_data
  ASoC: Intel: avs: Remove redundancy around DAI startup
  ASoC: Intel: avs: Remove redundancy around DAI prepare
  ASoC: Intel: avs: Store pointer to link_stream in dma_data
  ASoC: Intel: avs: Clean up hw constraints initialization
