The HDA driver cannot assume that the order that the devices are
specified in the cirrus,dev-index matches the order of calibration
entries.
Only a calibration entry with a matching silicon id will be used.

The driver doesn't create any ALSA controls for firmware controls, so it
shouldn't be calling hda_cs_dsp_control_remove().
commit 34e1b1bb7324 ("ALSA: hda: cs35l56: Stop creating ALSA controls for
firmware coefficients") removed the call to hda_cs_dsp_add_controls() but
didn't remove the call for destroying those controls.

A number of laptops have gone to market with old firmware versions that
export controls that have since been hidden, but we can't just install a
newer firmware because the firmware for each product is customized and
qualified by the OEM. The issue is that alsactl save and restore has no
idea what controls are good to persist which can lead to
misconfiguration.
There is no reason that the UCM or user should need to interact with any
of the ALSA controls for the firmware coefficients so they can be
removed entirely, this also simplifies the driver.

It is possible that during system boot when there multiple devices
attempting simultaneous initialization on a slow control bus the
download of firmware and tuning data may take a user perceivable amount
of time (a slow I2C bus with 4 amps this work could take over 2
seconds).
Adopt a pattern used in the ASoC driver and perform this activity in a
background thread so that interactive performance is not impaired. The
system_long_wq is a parallel workqueue and driver instances will perform
their firmware downloads in parallel to make best use of available bus
bandwidth.

The cs_dsp instance is initialized in the driver probe() so it
should be freed in the driver remove(). Also fix a missing call
to cs_dsp_remove() in the error path of cs35l56_hda_common_probe().
The call to cs_dsp_remove() was being done in the component unbind
callback cs35l56_hda_unbind(). This meant that if the driver was
unbound and then re-bound it would be using an uninitialized cs_dsp
instance.
It is best to initialize the cs_dsp instance in probe() so that it
can return an error if it fails. The component binding API doesn't
have any error handling so there's no way to handle a failure if
cs_dsp was initialized in the bind.

Check whether the firmware is already patched. If so, include the
firmware version in the firmware file name.
If the firmware has already been patched by the BIOS the driver
can only replace it if it has control of hard RESET.
If the driver cannot replace the firmware, it can still load a wmfw
(for ALSA control definitions) and/or a bin (for additional tunings).
But these must match the version of firmware that is running on the
CS35L56.
The firmware is pre-patched if either:
- FIRMWARE_MISSING == 0, or
- it is a secured CS35L56 (which implies that is was already patched),
cs35l56_hw_init() will set preloaded_fw_ver to the (non-zero)
firmware version if either of these conditions is true.
Normal (unpatched or replaceable firmware):
cs35l56-rev-dsp1-misc[-system_name].[wmfw|bin]
Preloaded firmware:
cs35l56-rev[-s]-VVVVVV-dsp1-misc[-system_name].[wmfw|bin]
Where:
[-s] is an optional -s added into the name for a secured CS35L56
VVVVVV is the 24-bit firmware version in hexadecimal.
Backport note:
This won't apply to kernel versions older than v6.6.

Change the filename field layout to:
cs35l56-rev[-s]-dsp1-misc[-sub].[wmfw|bin]
This is to keep the same firmware file naming scheme as the
CS35L56 ASoC driver.
This is not a compatibility break because no firmware files have
been published.
The original field layout matched the ASoC driver, but the way the
ASoC driver used the wm_adsp driver config to form this filename
was bugged. Fixing the ASoC driver to use the correct wm_adsp config
strings means that the 's' flag (to indicate a secured part) has to
move to somewhere after the first '-'.

Check for the cases of system-specific bin file without a
wmfw before falling back to looking for a generic wmfw.
All system-specific options should be tried before falling
back to loading a generic wmfw/bin. With the original code,
the presence of a fallback generic wmfw on the filesystem
would prevent using a system-specific tuning with a ROM

Add ASP1_FRAME_CONTROL1, ASP1_FRAME_CONTROL5 and the ASP1_TX?_INPUT
registers to the sequence used to initialize the ASP configuration.
Write this sequence to the cache and directly to the registers to
ensure that they match.
A system-specific firmware can patch these registers to values that are
not the silicon default, so that the CS35L56 boots already in the
configuration used by Windows or by "driverless" Windows setups such
as factory tuning.
These may not match how Linux is configuring the HDA codec. And anyway
on Linux the ALSA controls are used to configure routing options.

Add a KUnit test for cirrus_scodec_get_speaker_id(). It is impractical
to have enough hardware with every possible permutation of speaker id.
So use a test harness to test all theoretically supported options.
The test harness consists of:
- a mock GPIO controller.
- a mock struct device to represent the scodec driver
- software nodes to provide the fwnode info that would normally come
from ACPI.

Add handling of the "spk-id-gpios" _DSD property. If present, the
value indicated by the GPIOs is appended to the subsystem-id
part of the firmware name to load the appropriate tunings for that
speaker.
Some manufacturers use multiple sources of speakers, which need
different tunings for best performance. On these models the type
of speaker fitted is indicated by the values of one or more GPIOs.
The number formed by the GPIOs identifies the tuning required.
The speaker ID is only used in combination with a _SUB identifier
because the value is only meaningful if the exact model is known.
The code to get the speaker ID value has been implemented as a
new library so that the cs35l41_hda driver can be switched in
future to share common code. This library can be extended for
other common functionality shared by Cirrus Logic amp drivers.

In cs35l56_hda_read_acpi() do not return if ACPI _SUB is missing.
A missing _SUB means that the driver cannot load a system-specific
firmware, because the firmware is identified by the _SUB. But it can
fallback to a generic firmware. Unfortunately this was being handled
by immediately returning 0, which would skip the remaining ACPI
configuration in cs35l56_hda_read_acpi() and so it would not get the
RESET GPIO.

A RAM firmware can only be downloaded if the CS35L56 is currently
running from ROM firmware. The driver must not try to overwrite
the RAM if the CS35L56 is already running from that RAM.
Firmware can be downloaded in these two cases:
- The BIOS has already patched the firmware (secured mode).
In this case the firmware files will only contain tunings that
are safe to overwrite.
- The CS35L56 is running the built-in ROM firmware.
After a RAM firmware has been downloaded it can only be cleared by
hard resetting CS35L56. Some systems only hard-reset during
power-on and do not give the driver control of hard reset.

Always call cs_dsp_power_up() and cs_dsp_run() in
cs35l56_hda_fw_load() even if there aren't any firmware files
to download. Also, if there aren't any firmware files to
download there is no need to do cs35l56_firmware_shutdown() and
cs35l56_system_reset().
If there aren't any firmware files there's no need to write
anything to the CS35L56 registers to make it work - it will
already be running the ROM firmware. So it's not strictly
necessary to start cs_dsp.
But it's perfectly ok to call cs_dsp_power_up() and
cs_dsp_run() without downloading any firmware. This avoids
having to support a state where audio is playing but cs_dsp
is not running.

Only call regcache_mark_dirty() in cs35l56_hda_fw_load() if
the CS35L56 was SYSTEM_RESET.
recache_mark_dirty() changes the behaviour of regcache_sync()
to write out cache values that are not the default value, and
skip cache values that are the default.
AUDIO_REINIT does not reset the registers. regcache_mark_dirty()
after AUDIO_REINIT could cause the regcache_sync() to sync
registers incorrectly because it will assume that all registers
have reset to default.

Add a driver for the Cirrus Logic CS35L56 amplifier. This uses the same
component binding API as the CS35L41 driver. This is not a standalone
HDA device; it provides control of the CS35L56 for systems that use a
combination of an HDA codec and CS35L56 amplifiers with audio routed
through the HDA codec.
The CS35L56 combines a high-performance mono audio amplifier, Class-H
tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost
converter supporting Class-H tracking.
Control interfaces are I2C or SPI through the standard Linux I2C or SPI
bus framework.
Most chip functionality is controlled by on-board ROM firmware that is
always running. Firmware patches can be applied by the driver in the form
of a .wmfw file (firmware patch) and/or a .bin file (system tuning).
