The ACPI in some SoundWire laptops has a spk-id-gpios property but it points to the wrong Device node. This patch adds a workaround to try to get the GPIO directly from the correct Device node. If the attempt to get the GPIOs from the property fails, the workaround looks for the SDCA node "AF01", which is where the GpioIo resource is defined. If this exists, a spk-id-gpios mapping is added to that node and then the GPIO is got from that node using the property.

Rewrite the handling of ASP1 TX mixer mux initialization to prevent a deadlock during component_remove(). The firmware can overwrite the ASP1 TX mixer registers with system-specific settings. This is mainly for hardware that uses the ASP as a chip-to-chip link controlled by the firmware. Because of this the driver cannot know the starting state of the ASP1 mixer muxes until the firmware has been downloaded and rebooted. The original workaround for this was to queue a work function from the dsp_work() job. This work then read the register values (populating the regmap cache the first time around) and then called snd_soc_dapm_mux_update_power(). The problem with this is that it was ultimately triggered by cs35l56_component_probe() queueing dsp_work, which meant that it would be running in parallel with the rest of the ASoC component and card initialization. To prevent accessing DAPM before it was fully initialized the work function took the card mutex. But this would deadlock if cs35l56_component_remove() was called before the work job had completed, because ASoC calls component_remove() with the card mutex held. This new version removes the work function. Instead the regmap cache and DAPM mux widgets are initialized the first time any of the associated ALSA controls is read or written.

If the "spk-id-gpios" property is present it points to GPIOs whose value must be used to select the correct bin file to match the speakers. 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 must be used in combination with the subsystem ID (either from PCI SSID or cirrus,firmware-uid property), because the GPIOs can only indicate variants of a specific model.

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.

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.

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. Backport note: This won't apply cleanly to kernels older than v6.6.

The ASP1 DOUT line must be defaulted to be high-impedance when it is not actually transmitting data for an active channel. In non-SoundWire modes ASP1 will usually be shared by multiple amps so each amp must only drive the line during the slot for an enabled TX channel. In SoundWire mode a custom firmware can use ASP1 as a secondary chip-to-chip audio link or as GPIO. It should be defaulted to high-impedance since by default the purpose of this pin is not known.

If the driver properties do not define a cirrus,firmware-uid try to get the PCI SSID as the UID. On PCI-based systems the PCI SSID is used to uniquely identify the specific sound hardware. This is the standard mechanism for x86 systems and is the way to get a unique system identifier for systems that use the CS35L56 on SoundWire. For non-SoundWire systems there is no Windows equivalent of the ASoC driver in I2C/SPI mode. These would be: 1. HDA systems, which are handled by the HDA subsystem. 2. Linux-specific systems. 3. Composite devices where the cs35l56 is not present in ACPI and is configured using software nodes. Case 2 can use the firmware-uid property, though the PCI SSID is supported as an alternative, as it is the standard PCI mechanism. Case 3 is a SoundWire system where some other codec is the SoundWire bridge device and CS35L56 is not listed in ACPI. As these are SoundWire systems they will normally use the PCI SSID.

Use a device property "cirrus,firmware-uid" to get the unique firmware identifier instead of using ACPI _SUB. There aren't any products that use _SUB. There will not usually be a _SUB in Soundwire nodes. The ACPI can use a _DSD section for custom properties. There is also a need to support instantiating this driver using software nodes. This is for systems where the CS35L56 is a back-end device and the ACPI refers only to the front-end audio device - there will not be any ACPI references to CS35L56.

Re-implement setting of ASP TDM slots so that only the common loop to build the register word is factored out. The original cs35l56_set_asp_slot_positions() had an apparent uninitialized variable if the passed register address was neither of the ASP slot registers. In fact this would never happen because the calling code passed valid registers. While it's trivial to initialize the variable or add a default case, actually the only common code was the loop at the end of the function, which simply manipulates some mask values and is identical for either register. Factoring out the regmap_write() didn't really gain anything. So instead re-implement the code to replace the original function with cs35l56_make_tdm_config_word() that only does the loop, and change the calling code to call regmap_write() directly.

If the device is in secure mode it's unnecessary to send a SHUTDOWN and SYSTEM_RESET around the firmware download. It could only be patching insecure tunings. A tuning patch doesn't need a SHUTDOWN and only needs a REINIT afterwards. This will reduce the overhead of exiting system suspend in secure mode.

SoundWire bus accesses must be performed under the guard of a pm_runtime request, in this case the write was being performed just after the request had been put() and so the bus could not be guaranteed to be available.

Each time we go through dsp_work() it does a devm_kasprintf() to allocate memory to hold the part name string. It's not strictly a memory leak because devm will free it all if the driver is removed. But we keep allocating more and more memory to hold the same string. Move the allocation so that it is performed after the version and secured state information is gathered and handle allocation errors.

Flush the SoundWire interrupt handler work instead of cancelling it. When a SoundWire interrupt is triggered the pm_runtime is held until the work has completed. It's therefore unsafe to cancel the work, it must be flushed.
