Currently we set pipeline instance id = swidget->pipeline_id, but
pipeline_id is from topology and can be any number. In fact, the
number of pipelines is limited. This patch use ida to allocate pipeline

Some ASoC machine drivers for MediaTek platforms were not being
registered to the module device table, preventing them to be
automatically loaded when built as modules. This series adds the missing
registration to the drivers.

it can be automatically loaded when a matching device is found on the

During system suspend there is a chance that the running stream undergo
an xrun and instead of the expected SNDRV_PCM_TRIGGER_SUSPEND trigger
we will receive SNDRV_PCM_TRIGGER_STOP.
The handling of SUSPEND and STOP triggers differ that case of the later
the sof_pcm_stream_free() will be called with free_widget_list = false.
But we must make sure that all active widgets and streams are free before
entering suspend in order to be able to resume without error.
We can utilize the tear_down_all_pipelines to put the system to an expected
state and to fix the suspend/resume error.

Switch the driver from legacy gpio API that is deprecated to the newer
gpiod API that respects line polarities described in ACPI/DT.
The driver still tries to support shared reset lines, by first trying to
allocate the reset GPIO normally, and then non-exclusively, although the
utility of such support is questionable, toggling reset line from one
driver/instance will result in all chips being reset, potentially at an
inopportune moment.
Note that this change depends on commit fbbbcd177a ("gpiolib: of: add
quirk for locating reset lines with legacy bindings") to translate
request for "reset" GPIO to the legacy name "gpio-reset" in case when
proper name is not used.

.set_sysclk() is effectively unused here. No machine drivers use
jz4740-i2s; and JZ4740_I2S_CLKSRC_EXT is the only selectable clock
source with simple-card, but that is also the default source and
has a fixed frequency, so configuring it would be redundant.
simple-card ignores -ENOTSUPP error codes when setting the sysclock,
so any device trees that do set the sysclock for some reason should
still work.
It's still possible to configure the clock parent manually in the
device tree and control frequency using other simple-card options,
so at the end of the day there's no real loss in functionality.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Existing HDaudio controllers expose an HDAudio DMA which is used to
interface with HDaudio codecs. All other interfaces supported by Intel
(SoundWire, SSP, DMIC) rely for data transfers on another GP-DMA
managed by the DSP firmware - the HDaudio DMA is only used for
memory-to-DSP transfers.
New HDaudio extensions will enable the use of this HDaudio DMA for all
of SoundWire, SSP, DMIC. These extensions will be backwards-compatible
for HDaudio and iDISP codecs, but will require new programming
sequences and DAI callbacks for SoundWire, SSP and DMIC.
Before we add support for 'extended audio links' and the programming
sequences for the DMA, we need to refactor the code. All HDaudio codec
support needs to be well identified in a separate file, and likewise
all the 'multi-link' handling needs to be better split.
This patchset removes a number of 'old' Kconfig dependencies and
options, adds helpers with a fallback to remove IS_ENABLED checks in
the code and tries to simplify programming sequences when possible.
One indirect benefit from this refactoring is that developers can
switch with a kernel parameter from HDaudio support to a variant of
'nocodec' support. This proves extremely useful to test on existing
Intel RVPs and Up boards, where the same build can be used to check 3
interfaces (HDaudio, SSP, DMIC) by just removing modules, setting the
kernel parameter and reloading modules.
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Goal of the series is implementation of suspend/resume operations for a
PCM stream along with all the collaterals connected to the subject.
Start with splitting avs_dai_fe_hw_free() as ideally we would like to
reuse as much of existing code as possible but snd_pcm_lib_free_pages()
is not desired part of the function when speaking of suspend operation.
The actual implementation of suspend/resume() for component drivers
follows. For most scenarios, the PM flow is similar to standard
streaming one, except for the part where the position register are being
saved and the lack of PCM pages freeing. To reduce code duplication, all
avs_dai_suspend_XXX() and avs_dai_resume_XXX() functions reuse their
non-PM equivalents.
Order of operations is affected by the fact that path binding/unbinding
happens only in FE part of the stream.
Above essentially unlocks SX+streaming scenarios i.e.: power transitions
with an ongoing stream.
As some streams are allowed to run in low power state, support is
provided for S0iX state. The handlers check ACPI capabilities and the
number of active low-power paths before deciding between SX and S0iX
flows.
The last portion of the patchset is addition of power/clock gating
overrides. There is no single set of registers that ensures AudioDSP
firmware loads 100% of time on every single configuration. By having
them exposed, user can have the loading procedure behavior adjusted for
their configuration without having to recompile the kernel.
