The ACE3 IP used in PantherLake exposes new bitfields in the ACTMCTL
register to better control clocks/delays. These bitfields were
reserved/zero in the ACE2.x IP, to simplify the integration the new
bifields are added unconditionally. The behavior will only be impacted
when the firmware exposes DSD properties to set non-zero values.

In the MeteorLake hardware, the SoundWire link clock can be selected
from the Xtal, audio cardinal clock (24.576 MHz) or the 96 MHz audio
PLL.
This patches add the clock selection in a backwards-compatible manner,
using the ACPI firmware as the source of information and checking its
compatibility with hardware capabilities.

git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire
Pull soundwire updates from Vinod Koul:
"Device numbering and intel driver changes are main features:
- Core support for soundwire device number allocation
- intel driver updates for adding hw_params for DAI ops, hybrid
number allocation and power managemnt callback updates
- DT header include changes for subsystem"
* tag 'soundwire-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/soundwire:
soundwire: intel_ace2x: add DAI hw_params/prepare/hw_free callbacks
soundwire: intel_auxdevice: add hybrid IDA-based device_number allocation
soundwire: bus: add callbacks for device_number allocation
soundwire: extend parameters of new_peripheral_assigned() callback
soundWire: intel_auxdevice: resume 'sdw-master' on startup and system resume
soundwire: intel_auxdevice: enable pm_runtime earlier on startup
soundwire: Explicitly include correct DT includes

The IDA-based allocation is useful to simplify debug, but it was also
introduced as a prerequisite to deal with the Intel Lunar Lake
hardware programming sequences: the wake-ups have to be handled with a
system-unique SDI address at the HDaudio controller level.
At the time, the restriction introduced by the IDA to 8 devices total
seemed perfectly fine, but recently hardware vendors created
configurations with more than 8 devices.
Add a new allocation strategy to allow for more than 8 devices using
information on the type of devices, and only use the IDA-based
allocation for devices capable of generating a wake.
In theory the information on wake capabilities should come from
firmware, but none of the existing ACPI tables provide it. The drivers
set the 'wake_capable' property, but this cannot be used reliably: if
the driver probe happens *after* the enumeration, then that property
is not initialized yet. Trying to modify the device_number on-the-fly
proved to be an impossible task generating race conditions left and
right.
The only reliable work-around to control the enumeration is to add a
quirk table. It's ugly but until platform firmware improves, hopefully as a
result of MIPI/SDCA stardization, we can expect that quirk table to
grow for each new headset or microphone codec.

In existing Intel/SoundWire systems, all the SoundWire configuration
is 'self-contained', with the 'shim_lock' mutex used to protect access
to shared registers in multi-link configurations.
With the move of part of the SoundWire registers to the HDaudio
multi-link structure, we need a unified lock. The hda-mlink
implementation provides an 'eml_lock' that is used to protect shared
registers such as LCTL and LSYNC, we can pass it to the SoundWire
side. There is no issue with possible dangling pointers since the
SoundWire auxiliary devices are children of the PCI device, so the
'eml_lock' cannot be removed while the SoundWire side is in use.
This patch only adds the interface for now.

Before introducing new hardware with completely different register
spaces and programming sequences, we need to abstract some of the
existing routines in hw_ops that will be platform-specific. For now we
only use the 'cnl' ops - after the first Intel platform with SoundWire
capabilities.
Rather than one big intrusive patch, hw_ops are introduced in this
patch so show the dependencies between drivers. Follow-up patches will
introduce callbacks for debugfs, power and bus management.

We don't really need to pass a substream to the callback, we only need
the direction. No functionality change, only simplification to enable
improve suspend with paused streams.

Those Intel sdw registers will be used by ASoC SOF drivers in the
following commits. So move those definitions to sdw_intel.h and it can
be visible to SOF drivers.

Now that the auxiliary_bus exists, there's no reason to use platform
devices as children of a PCI device any longer.
This patch refactors the code by extending a basic auxiliary device
with Intel link-specific structures that need to be passed between
controller and link levels. This refactoring is much cleaner with no
need for cross-pointers between device and link structures.
Note that the auxiliary bus API has separate init and add steps, which
requires more attention in the error unwinding paths. The main loop
needs to deal with kfree() and auxiliary_device_uninit() for the
current iteration before jumping to the common label which releases
everything allocated in prior iterations.

The ACPI scan capabilities is called from the intel-dspconfig as well
as the SOF/HDaudio drivers. This creates dependencies and randconfig issues
when HDaudio and SOF/SoundWire are not all configured as modules.
To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and
intel-dspconfig, move the ACPI scan helpers to a dedicated
module. This follows the same idea as NHLT helpers which are already
handled as a dedicated module.
The only functional change is that the kernel parameter to filter
links is now handled by a different module, but that was only provided
for developers needing work-arounds for early BIOS releases.

Somehow the existing code is not aligned with the steps described in
the documentation, refactor code and make sure the register
programming sequences are correct. Also add missing power-up,
power-down and wake capabilities (the last two are used in follow-up
patches but introduced here for consistency).
Some of the SHIM registers exposed fields that are link specific, and
in addition some of the power-related registers (SPA/CPA) take time to
be updated. Uncontrolled access leads to timeouts or errors. Add a
mutex, shared by all links, so that all accesses to such registers are
serialized, and follow a pattern of read-modify-write.
This includes making sure SHIM_SYNC is programmed only once, before
the first master is powered on. We use a 'shim_mask' field, shared
between all links and protected by a mutex, to deal with power-up and
power-down sequences.
Note that the SYNCPRD value is tied only to the XTAL value and not the
current bus frequency or the frame rate.

The existing link_mask flag is no longer sufficient to detect the
hardware and identify which topology file and a machine driver to load.
By reporting the slave_ids exposed in ACPI tables, the parent SOF
driver will be able to compare against a set of static configurations.
This patch only adds the interface change, the functionality is added
in future patches.

Due to power rail dependencies, the SoundWire Master driver cannot
make decisions on its own when entering pm runtime suspend.
Add quirk mask for each link, so that the SOF parent driver can inform
the SoundWire master driver of the desired behavior:
a) leave clock on
b) power-off instead of clock stop
c) power-off if all devices cannot generate wakes
d) force bus reset on clock restart
Note that for now the interface with the SOF driver relies on a single
mask for all links. If needed, the interface might be modified at a
later point to provide more freedom. The code at the lower level does
not assume any commonality between links.

Some of the Intel SoundWire SHIM registers contain fields for
different links. Without protection, the master drivers for the
different links will access these shared registers, leading to invalid
configurations and timeouts (specifically when changing CPA/SPA
power-related registers and polling for the changes to be applied).
A mutex is added to make sure all rmw access to those registers are
serialized.

In MSI mode, the use of separate handlers and threads for the Intel
IPC, stream and SoundWire shared interrupt leads to timeouts and lost
interrupts.
The solution is to merge all interrupt handling across all links with
a single thread function. The use of a linked list enables this thread
function to walk through all contexts and figure out which link needs
attention.
