5eb4ff884f ALSA: hda: Add code_loading parameter to stream setup
AudioDSP firmware is the one who kicks SDxFIFOS calculation when a
stream is decoupled mode. During firmware bring up procedure, there is
no firmware running and the code-loading stream is always a decoupled
one. So, there is none to trigger the calculation and we end up with
false-positive timeout (-110) messages.

88320b74ef ALSA: hda: Introduce HOST stream setup mechanism
HDAudio stream setup procedure differs between revisions of the
controller device. Currently the differences are handled directly within
AudioDSP platform drivers with if-statements. Implement a more generic
approach and expose a function that a platform driver may use to ensure
the correct procedure is followed each time.

ALSA: hda: Allow for compress stream to hdac_ext_stream assignment
Currently only PCM streams can enlist hdac_stream for their data
transfer. Add cstream field to hdac_ext_stream to expose possibility of
compress stream assignment in place of PCM one.
Limited to HOST-type only as there no other users on the horizon.

6258234129 ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer
The SPIB and DRMS capabilities are orthogonal to the DSP enablement
and can be used whether the stream is coupled or not.

The existing code partitioning makes limited sense, the capabilities
are parsed at the sound/hda level but helpers are located in
sound/hda/ext.

This patch moves all the SPIB/DRMS functionality to the sound/hda
layer. This reduces the complexity of the sound/hda/ext layer which is
now limited to handling the multi-link extensions and stream
coupling/decoupling helpers.

Note that this is an iso-functionality code move and rename, the
HDaudio legacy driver would need additional changes to make use of
these capabilities.

26646c199b ALSA: hda: ext: reduce ambiguity between 'multi-link' and 'link' DMA
My esteemed colleagues keep using the same words for different things.

The multi-link structure needs to be handled whether the DSP is
enabled or not.

The host and link DMAs are only relevant when the DSP is enabled.

Things get convoluted when there's an ambiguity between the LOSIDV
settings in the multi-link register space and the selection of the
stream_tag for the link DMA.

Clarify with a rename that the static functions used are related to
the host and link DMAs only.

No functionality change, pure rename.

7fa403f2a0 ALSA/ASoC: hda: ext: add 'bus' prefix for multi-link stream setting
All the helpers dealing with multi-link configurations are located in
the hdac_ext_controller.c, except the two set/clear routines that
modify the LOSIDV registers.

For consistency, move the two helpers and add the 'bus' prefix. One
could argue that the 'ml' prefix might be more relevant but that would
be a larger code change.

No functionality change, just move and rename.

ac3467ad7f ALSA: hda: ext: fix locking in stream_release
The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but
releases it before calling snd_hdac_stream_release() where the bus
reg_lock is taken again.

This creates a timing window where the link stream release could test
an invalid 'opened' boolean status and fail to recouple the host and
link parts.

Fix by exposing a locked version of snd_hdac_stream_release() and use
it without releasing the spinlock.

53f4f6b4e5 ALSA: hda: ext: simplify logic for stream assignment
The logic is needlessly complicated, the basic rule is:

The host streams can be found by checking the 'opened' boolean.
The link streams can be found by checking the 'link_locked' boolean.

Once a stream is found, it can be unconditionally decoupled. The
snd_hdac_ext_stream_decouple_locked() routine will make sure the
register status is modified as needed and the 'decoupled' boolean set.

0f7e5ee62f ALSA: HDA: hdac_ext_stream: use consistent prefixes for variables
The existing code maximizes confusion by using 'stream' and 'hstream'
variables of different types. Examples:

struct hdac_stream *stream;
struct hdac_ext_stream *stream;
struct hdac_stream *hstream;
struct hdac_ext_stream *hstream;

with some additional copy/paste remains:
struct hdac_ext_stream *azx_dev;

This patch suggests a consistent naming across all 'hdac_ext_stream'
functions. The convention is:

struct hdac_stream *hstream;
struct hdac_ext_stream *hext_stream;

No functionality change - just renaming of variables and more
consistent indentation.

868ddfcef3 ALSA: hda: hdac_ext_stream: fix potential locking issues
The code for hdac_ext_stream seems inherited from hdac_stream, and
similar locking issues are present: the use of the bus->reg_lock
spinlock is inconsistent, with only writes to specific fields being
protected.

Apply similar fix as in hdac_stream by protecting all accesses to
'link_locked' and 'decoupled' fields, with a new helper
snd_hdac_ext_stream_decouple_locked() added to simplify code
changes.

The drivers need to set the spib and maxfifios values, so add
these new APIs snd_hdac_ext_stream_set_spib() and
snd_hdac_ext_stream_set_spbmaxfifo() APIs

For these APIs we also need to have spib and fifos pointer, so
add these to hdac_ext_stream and initialize them at stream init

SPCAP and Mutilink register offset were incorrect as offset needs
to be based on capability offset. So correct the offset for
read/write of spcap/link register.

e7a3484dc5 ALSA: hda: add hdac_ext stream creation and cleanup routines
HDAC extended core should create streams for an extended bus and also free
up those on cleanup. So introduce snd_hdac_ext_stream_init_all and
snd_hdac_stream_free_all routines

df203a4e46 ALSA: hdac_ext: add extended stream capabilities
Now we have the bus and controller code added to find and initialize
the extended capabilities. Now we need to use them in stream code to
decouple stream, manage links etc

So this patch adds the stream handling code for extended capabilities
introduced in preceding patches
