d344873c4c ALSA: hda: cs35l56: Fix lifetime of cs_dsp instance
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.

ALSA: hda: cs35l56: Exit cache-only after cs35l56_wait_for_firmware_boot()
Adds calls to disable regmap cache-only after a successful return from
cs35l56_wait_for_firmware_boot().

This is to prepare for a change in the shared ASoC module that will
leave regmap in cache-only mode after cs35l56_system_reset(). This is
to prevent register accesses going to the hardware while it is
rebooting.

ALSA: hda: cs35l56: Firmware file must match the version of preloaded firmware
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.

ALSA: hda: cs35l56: Fix filename string field layout
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 '-'.

All system-specific options should be tried before falling

the presence of a fallback generic wmfw on the filesystem

registers to the sequence used to initialize the ASP configuration.
Write this sequence to the cache and directly to the registers to

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.

- a mock struct device to represent the scodec driver
- software nodes to provide the fwnode info that would normally come

6f03b446cb ALSA: hda: cs35l56: Add support for speaker id
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.

21484e43b9 ALSA: hda: cs35l56: Fix missing RESET GPIO if _SUB is missing
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.

If there aren't any firmware files there's no need to write

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

having to support a state where audio is playing but cs_dsp
is not running.

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.

ALSA: hda/cs35l56: Add driver for Cirrus Logic CS35L56 amplifier
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).
