2025-06-12ASoC: cs35l56: Use SoundWire address as alternate firmware suffix on L56 B0Richard Fitzgerald
Use the SoundWire link number and device unique ID as the firmware file qualifier suffix on CS35L56 B0 if .bin files are not found with the older suffix. Some changes in wm_adsp needed to support this have been included in this patch because they are trivial. The allows future products with CS35L56 B0 silicon to use the same firmware file naming as CS35L57 and cs35L63, while retaining backward compatibility for firmware that has already been published with the old naming scheme. The old suffix is searched first, partly because there are already many files using that naming scheme, but also because they are a smaller subset of all the possible fallback name options offered by wm_adsp so we know that it will either find the qualified files or fail. All the firmware files already published have the wmfw qualified with only the ACPI SSID and the bin files qualified with both SSID and the suffix. Originally, the firmware file names indicated which amplifier instance they were for by appending the ALSA prefix string. This is the standard ASoC way of distinguishing different instances of the same device. However, on SoundWire systems the SoundWire physical unique address is available as a unique identifier for each amp, and this address is hardwired by the address pin on the amp. The firmware files are specific for each physical amp so they must be applied to that amp. Using the ALSA prefix for the filename qualifier means that to name a firmware file it must be determined what prefix string the machine driver will assign to each device and then use that to name the firmware file correctly. This is straightforward in traditional ASoC systems where the machine driver is specific to a particular piece of hardware. But on SoundWire the machine driver is generic and can handle a very wide range of hardware. It is more difficult to determine exactly what the prefix will be on any particular production device, and more prone to mistakes. Also, when the machine driver switches to generating this automatically from SDCA properties in ACPI, there is an additional layer of complexity in determining the mapping. This uncertainty is unnecessary because the firmware is built for a specific amp. with known address, so we can use that directly instead of introducing a redundant intermediate alias. This ensures the firmware is applied to the amp it was intended for. There are already many published firmware for CS35L56 B0 silicon so this first looks for the original name suffix, to keep backward compatibility. If this doesn't find .bin files it will switch to using the new name suffix so that future products using CS35L56 B0 can start to use the new suffix.

2025-06-12ASoC: cs35l56: Use SoundWire address as firmware name suffix for new siliconRichard Fitzgerald
Use the SoundWire link number and device unique ID as the firmware file qualifier suffix on CS35L57, CS35L63 and revisions of CS35L56 after B0. The change in wm_adsp needed to support this has been included in this patch because it is fairly trivial. Originally, the firmware file names indicated which amplifier instance they were for by appending the ALSA prefix string. This is the standard ASoC way of distinguishing different instances of the same device. However, on SoundWire systems the SoundWire physical unique address is available as a unique identifier for each amp, and this address is hardwired by a pin on the amp. The firmware files are specific for each physical amp so they must be applied to that amp. Using the ALSA prefix for the filename qualifier means that to name a firmware file it must be determined what prefix string the machine driver will assign to each device and then use that to name the firmware file correctly. This is straightforward in traditional ASoC systems where the machine driver is specific to a particular piece of hardware. But on SoundWire the machine driver is generic and can handle a very wide range of hardware. It is more difficult to determine exactly what the prefix will be on any particular production device, and more prone to mistakes. Also, when the machine driver switches to generating this automatically from SDCA properties in ACPI, there is an additional layer of complexity in determining the mapping. This uncertainty is unnecessary because the firmware is built for a specific amp. with known address, so we can use that directly instead of introducing the redundant intermediate alias. This ensures the firmware is applied to the amp it was intended for. There have not been any firmwares published for CS35L57 or CS35L63, so these can safely be switched to using the SoundWire unique address as the suffix string. Also note that the machine driver in older kernel version only has match entries for the CS35L56 Soundwire identity so any future product with a cs35L57 or CS35L63 would require a new kernel anyway. There are already many published firmware for CS35L56 B0 silicon so this keeps the original naming scheme on those, to preserve backward compatibility. Note that although sdw_slave.id contains a unique_id field, this cannot be trusted because the SoundWire core code also puts magic values into it that it uses as a flag. So the unique ID is read from the chip register.

2024-02-01ASoC: wm_adsp: Don't overwrite fwf_name with the defaultRichard Fitzgerald
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.

2022-06-30ASoC: wm_adsp: Minor clean and redundant code removalCharles Keepax
The cs_dsp core will return an error if passed a NULL cs_dsp struct so there is no need for the wm_adsp_write|read_ctl functions to manually check that. The cs_dsp core will also check the data is within bounds of the control so the additional bounds check is redundant too. Simplify things a bit by removing said code.

Currently wm_adsp_fw_put() returns 0 rather than 1 when updating the value of the control, meaning that no event is generated to userspace. Fix this by setting the default return value to 1, the code already exits early with a return value of 0 if the value is unchanged.

The compressed stream code has a bunch of structs that are used to represent DSP memory but have not been marked __packed. This isn't safe, they could get padded on a 64-bit build.

2022-03-07ASoC: wm_adsp: Expand firmware loading search optionsSimon Trimmer
The parts supported by this driver can have product-specific firmware and tunings files. Typically these have been used on embedded systems where the manufacturer is responsible for installing the correct product-specific firmware files into /lib/firmware. However, the linux-firmware repository places all available firmwares into /lib/firmware and it is up to the driver to select the correct product-specific firmware from that directory. For example a product containing four smart amplifiers may provide firmware specific for that product and each of the amplifiers may have coefficient files containing tunings for their placement in the mechanical design. This change extends firmware (wmfw) and coefficient (bin) filenames to be of the general form: <cirrus/>part-dspN-fwtype<-system_name<-asoc_component_prefix>>.type Where the cirrus subdirectory, system_name and asoc_component_prefix are optional. New files will be placed in the cirrus subdirectory to avoid polluting the main /lib/firmware/ location. The generic name must be searched in /lib/firmware before /lib/firmware/cirrus so that a generic file in the new location does not override existing product-specific files in the legacy location. The search order for firmware files is: - cirrus/part-dspN-fwtype-system_name-asoc_component_prefix.wmfw - cirrus/part-dspN-fwtype-system_name.wmfw - part-dspN-fwtype.wmfw - cirrus/part-dspN-fwtype.wmfw - Qualifications are added to the filename so that rightwards is more specific. - The system_name is provided by the codec driver. - The asoc_component_prefix is used to identify tunings for individual parts because it would already exist to disambiguate the controls and it makes it obvious which firmware file applies to which device. The optional coefficient file must have the same filename construction as the discovered wmfw except: - where the wmfw has only system_name then the bin file can optionally include the asoc_component_prefix. This is to allow a common wmfw for all amps but separate tunings per amp.

Newer firmwares will support compressed buffers that may or may not exist, for example debugging streams. Update the driver to make a compressed stream optional.

2022-02-10ASoC: wm_adsp: Correct control read size when parsing compressed bufferCharles Keepax
When parsing the compressed stream the whole buffer descriptor is now read in a single cs_dsp_coeff_read_ctrl; on older firmwares this descriptor is just 4 bytes but on more modern firmwares it is 24 bytes. The current code reads the full 24 bytes regardless, this was working but reading junk for the last 20 bytes. However commit f444da38ac92 ("firmware: cs_dsp: Add offset to cs_dsp read/write") added a size check into cs_dsp_coeff_read_ctrl, causing the older firmwares to now return an error. Update the code to only read the amount of data appropriate for the firmware loaded.

2022-01-05ASoC: wm_adsp: Add support for "toggle" preloadersCharles Keepax
In the case a device can support retaining the firmware memory across low power states it is useful for the preloader widget to only power up whilst actually loading/unloading the core, as opposed to the normal operation where the widget is powered for the entire time a firmware is preloaded onto the core. Add support for this mode and a flag to enable it.
