The following series adds the core support to handle the recently updated
HDaudio multi-link support to hanlde non HDA links, like SoundWire/DMIC/SSP on
Intel platform.
For details, please see the first patch which documents the current mlink
support (introduced at Skylake) and the new extensions, arriving with LNL.
There is no change in functionality for existing HDA support, the extension is
backwards compatible with existing implementations.

Each SoundWire peripheral can be programmed from the manager side
either with a regular command FIFO, or with the HDaudio CORB/RIRB
DMA-based mechanism. The mapping between SoundWire peripheral and SDI
address is handled with the LSDIID register.
This mapping only works of course if each peripheral has a unique
address across all links. This has already been enforced in previous
Intel contributions allowing for an IDA-based solution for the device
number allocation.
The checks on the dev_num are handled at the SoundWire level, but the
locking is handled at the hda-mlink level.

These helpers configure the ratio between the base clock and the
hardware signal used for link synchronization.
The SYNCPRD is written before the first sublink is powered-up. The
SYNCPU bit is set, but it will only be cleared after the link is
powered-up, hence the implementation with a set/wait pattern.
These helpers are currently only needed by SoundWire support, where
the lock is taken at a higher level, so only the _unlocked versions
are exposed for now.
Note that the _wait_bit() implementation is similar to previous
helpers in drivers/soundwire, but with sleep duration and timeout
aligned with hardware recommendations. If desired, this helper could
be modified in a second step with e.g. readl_poll_timeout().

Add helpers to program SPA/CPA bits, using a mutex to access the
shared LCTL register if required.
All links are managed with the same LCTLx.SPA bits. However there are
quite a few implementation details to be aware of:
Legacy HDaudio multi-links are powered-up when exiting reset, which
requires the ref_count to be manually set to one when initializing the
link.
Alternate links for SoundWire/DMIC/SSP need to be explicitly
powered-up before accessing the SHIM/IP/Vendor-Specific SHIM space for
each sublink. DMIC/SSP/SoundWire are all different cases with a
different device/dai/hlink relationship.
SoundWire will handle power management with the auxiliary device
resume/suspend routine. The ref_count is not necessary in this case.
The DMIC/SSP will by contrast handle the power management from DAI
.startup and .shutdown callbacks.
The SSP has a 1:1 mapping between sublink and DAI, but it's
bidirectional so the ref_count will help avoid turning off the sublink
when one of the two directions is still in use.
The DMIC has a single link but two DAIs for data generated at
different sampling frequencies, again the ref_count will make sure the
two DAIs can be used concurrently.
And last the SoundWire Intel require power-up/down and bank switch to
be handled with a lock already taken, so the 'eml_lock' is made
optional with the _unlocked versions of the helpers.
Note that the _check_power_active() implementation is similar to
previous helpers in sound/hda/ext, with sleep duration and timeout
aligned with hardware recommendations. If desired, this helper could
be modified in a second step with .e.g. readl_poll_timeout()

Extend hdac_ext_link to store information needed for ALT
links. Follow-up patches will include more functional patches for
power-up and down.
Note that this patch suggests the use of an 'eml_lock' to serialize
access to shared registers. SoundWire-specific sequence require the
lock to be taken at a higher level, as a result the helpers added in
follow-up patches will provide 'unlocked' versions when needed.
Also note that the low-level sequences with the 'hdaml_' prefix are
taken directly from the hardware specifications - naming conventions
included. The code will be split in two, with locking and linked-list
management handled separately to avoid mixing required hardware setup
and Linux-based resource management.

Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:
Click/Pop Noise was a long pending issue with WSA Codecs which are prone
to accumlate DC when ports are active but without any data streams.
There are multiple places in the current setup, where this could happen
in both startup as well as shutdown path.
dapm_connect_dai_pair() handles
"Normal/Codec2Codec" x "CPU/Codec" x "Playback/Capture".
(A) is "Codec2Codec" case of "CPU" widget x "Playback/Capture",
(B) is "Normal" case of "CPU" widget x "Playback/Capture",
(C) is each case of "Codec" widget.
(X) is handling "Playback" case DAI connecting,
(Y) is handling "Capture" case DAI connecting.
static void dapm_connect_dai_pair(...)
{
...
(A) if (dai_link->params) {
playback_cpu = ...
capture_cpu = ...
(B) } else {
playback_cpu = ...
capture_cpu = ...
}
^ /* connect BE DAI playback if widgets are valid */
| stream = SNDRV_PCM_STREAM_PLAYBACK;
| (C) codec = codec_dai->playback_widget;
|
| if (playback_cpu && codec) {
(X) if (dai_link->params && !rtd->c2c_widget[stream]) {
| ...
| }
|
| (z) dapm_connect_dai_routes(...);
v }
capture:
^ /* connect BE DAI capture if widgets are valid */
| stream = SNDRV_PCM_STREAM_CAPTURE;
| (C) codec = codec_dai->capture_widget;
|
| if (codec && capture_cpu) {
(Y) if (dai_link->params && !rtd->c2c_widget[stream]) {
| ...
| }
|
| (z) dapm_connect_dai_routes(...);
v }
}
(X) part and (Y) part are almost same.
Main purpose of these parts (and this function) is calling
dapm_connect_dai_routes() (= z) on each cases.
The difference is "parameter"
(= Normal/Codec2Codec x CPU/Codec x Playback/Capture).
This patch cleanup these, but nothing changed for meaning.

ASoC is supporting Codec2Codec, but its parameter name is
"params" and "num_params" which are very unclear naming.
This patch-set clarifies it by replacing to c2c_params / num_c2c_params.
