[PATCH v2 00/15] ASoC: Intel: avs: Driver core and PCM operations

[Cezary Rojewski]

Part three of main AVS driver series. This series was originally part of
the initial series which was later divided [1] into smaller,
easier-to-review chunks. Thus, many patches found here were already
present on the list.

This series consists of code typical to many drivers - PCI driver
operations, trace ability, PM operations - as well as PCM handlers for
all standard audio interfaces, that is, HDA, I2S and DMIC are found
here.

Series starts with updating firmware boot flow - libraries are no longer
ignored. This change is dependent on already merged topology code [2]
and because of that could not be part of the initial series [1].

PCM operations are split into four changes. First component operations
alone i.e. operations which are usually agnostic towards path position
(FE/BE). Then it continues with "generic" FE operations - there is no
interface split here as from Intel ADSP point of view, FE, or HOST side
as it's called in the specs, involves HD-Audio operations only.
BE (also known as LINK) side on the other hand is divided into
"non-HD-Audio" and HD-Audio part. The former represents transfer over
DMIC and I2S interfaces both.

While patches implementing standard PCI driver operations along (again
standard) HD-Audio initialization routines followed up by power
management handlers are two major ones, series covers also other
important subjects such as:

While patches implementing standard PCI driver operations along (again
standard) HD-Audio initialization routines followed up by power
management handlers are two major ones, series covers also other
important subjects such as:

- event tracing
- preparation for firmware tracing (debugability)
- coredump (debugability)
- recovery flow (attempt recovery after IPC timeout or exception)
- D0ix (D0 device substate, complements standard power management)

Series is finalized by actual addition of supported platforms: SKL and
APL-based. Platform-specific files are limited to firmware-specific
bits, that is, bits that are specific to given firmware generation.
Everything else is shared and is part of already upstream messaging
code found in ipc.c, messages.c and messages.h files.


Changes in v2:
- usage of avs_releast_last_firmware() dropped in error path for library
  loading procedure as suggested by Pierre
- 'link_mask' usage replaced with 'i2s_link_mask' as requested by
  Pierre. Existing code addressed with new patch:
  "ASoC: Intel: avs: Replace link_mask usage with i2s_link_mask"
- fixed possible race during recovery flow (->recovering flag is now
  atomic and tested in single location only).
- dropped platform prefixes for basically all i2s board descriptors
- 'ssp_test' renamed to 'i2s_test' to match naming convention of other
  boards
- simplified PM implementation for current series, 'low_power' bits
  moved to future series
- replaced SND_INTEL_DSP_DRIVER_SST with _AVS as suggested by Mark.
  Required changes to intel-dspcfg will be added in future series
- number of typos across commit messages addressed
