Check during initialization whether the firmware is already patched.
If so, include the firmware version in the wm_adsp fwf_name string.

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 FIRMWARE_MISSING == 0.

Including the firmware version in the fwf_name string will
qualify the firmware file name:

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.

Put the silicon revision and secured flag in the wm_adsp fwf_name
string instead of including them in the part string.

This changes the format of the firmware name string from

 cs35l56[s]-rev-misc[-system_name]

to
 cs35l56-rev[-s]-misc[-system_name]

No firmware files have been published, so this doesn't cause a
compatibility break.

Silicon revision and secured flag are included in the firmware
filename to pick a firmware compatible with the part. These strings
were being added to the part string, but that is a misuse of the
string. The correct place for these is the fwf_name string, which
is specifically intended to select between multiple firmware files
for the same part.

Defer initializing the state of the ASP1 mixer registers until
the firmware has been downloaded and rebooted.

On a SoundWire system the ASP is free for use as a chip-to-chip
interconnect. This can be either for the firmware on multiple
CS35L56 to share reference audio; or as a bridge to another
device. If it is a firmware interconnect it is owned by the
firmware and the Linux driver should avoid writing the registers.
However, if it is a bridge then Linux may take over and handle
it as a normal codec-to-codec link. Even if the ASP is used
as a firmware-firmware interconnect it is useful to have
ALSA controls for the ASP mixer. They are at least useful for
debugging.

CS35L56 is designed for SDCA and a generic SDCA driver would
know nothing about these chip-specific registers. So if the
ASP is being used on a SoundWire system the firmware sets up the
ASP mixer registers. This means that we can't assume the default
state of these registers. But we don't know the initial state
that the firmware set them to until after the firmware has been
downloaded and booted, which can take several seconds when
downloading multiple amps.

DAPM normally reads the initial state of mux registers during
probe() but this would mean blocking probe() for several seconds
until the firmware has initialized them. To avoid this, the
mixer muxes are set SND_SOC_NOPM to prevent DAPM trying to read
the register state. Custom get/set callbacks are implemented for
ALSA control access, and these can safely block waiting for the
firmware download.

After the firmware download has completed, the state of the
mux registers is known so a work job is queued to call
snd_soc_dapm_mux_update_power() on each of the mux widgets.

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

as factory tuning.

These may not match how Linux is configuring the HDA codec. And anyway

Patch the SDW TX mixer registers to silicon defaults.

CS35L56 is designed for SDCA and a generic SDCA driver would
know nothing about these chip-specific registers. So the
firmware sets up the SDW TX mixer registers to whatever audio
is relevant on a specific system.

This means that the driver cannot assume the initial values
of these registers. But Linux has ALSA controls to configure
routing, so the registers can be patched to silicon default and
the ALSA controls used to select what audio to feed back to the
host capture path.

Add a dummy SUPPLY widget connected to the ASP that forces the
chip registers to match the regmap cache when the ASP is
powered-up.

On a SoundWire system the ASP is free for use as a chip-to-chip
interconnect. This can be either for the firmware on multiple
CS35L56 to share reference audio; or as a bridge to another
device. If it is a firmware interconnect it is owned by the
firmware and the Linux driver should avoid writing the registers.
However. If it is a bridge then Linux may take over and handle
it as a normal codec-to-codec link.

ASP registers. This means that we can't assume the default
state of the ASP registers. But we don't know the initial state
that the firmware set them to until after the firmware has been
downloaded and booted, which can take several seconds when
downloading multiple amps.

To avoid blocking probe() for several seconds waiting for the
firmware, the silicon defaults are assumed. This allows the machine
driver to setup the ASP configuration during probe() without being
blocked. If the ASP is hooked up and used, the SUPPLY widget
ensures that the chip registers match what was configured in the
regmap cache.

If the machine driver does not hook up the ASP, it is assumed that
it won't call any functions to configure the ASP DAI. Therefore
the regmap cache will be clean for these registers so a
regcache_sync() will not overwrite the chip registers. If the
DAI is not hooked up, the dummy SUPPLY widget will not be
invoked so it will never force-overwrite the chip registers.

Remove the check of fw_patched from cs35l56_is_fw_reload_needed().
Also remove the redundant check for control of the reset GPIO.

The fw_patched flag is set when cs35l56_dsp_work() has completed its
steps to download firmware and power-up wm_adsp. There was a check in
cs35l56_is_fw_reload_needed() to make a quick exit of 'false' if
!fw_patched. The original idea was that the system might be suspended
before the driver has ever made any attempt to download firmware, and
in that case the driver doesn't need to return to a patched state
because it was never in a patched state.

This check of fw_patched is buggy because it prevented ever recovering
from a failed patch. If a previous attempt to patch and reboot the
silicon had failed it would leave fw_patched==false. This would mean
the driver never attempted another download even though the fault may
have been cleared (by a hard reset, for example).

It is also a redundant check because the calling code already makes
a quick exit if cs35l56_component_probe() has not been called, which
deals with the original intent of this check but in a safer way.

The check for reset GPIO is redundant: if the silicon was hard-reset
the FIRMWARE_MISSING flag will be 1. But this check created an
expectation that the suspend/resume code toggles reset. This can't
easily be protected against accidental code breakage. The only reason
for the check was to skip runtime-resuming the driver to read the
PROTECTION_STATUS register when it already knows it reset the silicon.
But in that case the driver will have to be runtime-resumed to do
the firmware download. So it created an assumption for no benefit.

There's no need to overwrite fwf_name with a kstrdup() of the cs_dsp part
name. It is trivial to select either fwf_name or cs_dsp.part as the string
to use when building the filename in wm_adsp_request_firmware_file().

This leaves fwf_name entirely owned by the codec driver.

It also avoids problems with freeing the pointer. With the original code
fwf_name was either a pointer owned by the codec driver, or a kstrdup()
created by wm_adsp. This meant wm_adsp must free it if it set it, but not
if the codec driver set it. The code was handling this by using
devm_kstrdup().
But there is no absolute requirement that wm_adsp_common_init() must be
called from probe(), so this was a pseudo-memory leak - each new call to
wm_adsp_common_init() would allocate another block of memory but these
would only be freed if the owning codec driver was removed.

Pull drm fixes from Dave Airlie:
 "Lots going on for rc2, ivpu has a bunch of stabilisation and debugging
  work, then amdgpu and xe are the main fixes. i915, exynos have a few,
  then some misc panel and bridge fixes.

  Worth mentioning are three regressions. One of the nouveau fixes in
  6.7 for a serious deadlock had side effects, so I guess we will bring
  back the deadlock until I can figure out what should be done properly.
  There was a scheduler regression vs amdgpu which was reported in a few
  places and is now fixed. There was an i915 vs simpledrm problem
  resulting in black screens, that is reverted also.

  I'll be working on a proper nouveau fix, it kinda looks like one of
  those cases where someone tried to use an atomic where they should
  have probably used a lock, but I'll see.

Pull spi fixes from Mark Brown:
 "As well as a few device IDs and the usual scattering of driver
  specific fixes this contains a couple of core things.

  One is a missed case in error handling, the other patch is a change
  from me raising the number of chip selects allowed by the newly added
  multi chip select support patches to resolve problems seen on several
  systems that exceeded the limit.

  This is not a real solution to the issue but rather just a change to
  avoid disruption to users, one of the options I am considering is just
  sending a revert of those changes if we can't come up with something
  sensible"
