The driver never uses the IRQ1_CFG register so there's no need to provide a default value. It's set as a readable register only for debugging through the regmap registers file. A system-specific firmware could overwrite this register with a non-default value. Therefore the driver can't hardcode what the initial value actually is. As the register is only for debugging the value can be left unknown until someone wants to read it through debugfs. Signed-off-by:

With the change in the widget free logic to power down the cores only when the scheduler widgets are freed, we need to ensure that the scheduler widget is freed only after all the widgets associated with the scheduler are freed. This is to ensure that the secondary core that the scheduler is scheduled to run on is kept powered on until all widgets that need them are in use. While this works well for dynamic pipelines, in the case of static pipelines the current logic does not take this into account and frees all widgets in the order they occur in the widget_list. So, modify this to ensure that the scheduler widgets are freed only after all other types of widgets in the widget_list are freed.

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. Signed-off-by:

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.

The number formed by the GPIOs identifies the tuning required.

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 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. Signed-off-by:

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

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. Signed-off-by:

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.
