Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: This is the part1 of my HDaudio cleanups, before the addition of to-be-announced HDaudio extensions. The patchset includes more consistent use of read/write/update helpers, removal of useless waits, structure members and programming sequences, removal of confusing sharing of private_data between FE and BE. Additional patches are coming to split the controller, codec and multi-link management functionality in well-identified files.

Merge series from Aidan MacDonald <aidanmacdonald.0x0@gmail.com>: This series is a preparatory cleanup of the jz4740-i2s driver before adding support for a new SoC. The two improvements are lifting unnecessary restrictions on sample rates and formats -- the existing ones appear to be derived from the limitations of the JZ4740's internal codec and don't reflect the actual capabilities of the I2S controller. I'm unable to test the series on any JZ47xx SoCs, but I have tested on an X1000 (which is the SoC I'll be adding in a followup series).

Although the FIFO doesn't care about the in-memory sample format, we only support 4-byte format variants because the DMA controller on these SoCs cannot transfer in 3-byte multiples.

On the JZ4740, there is a single bit that flushes (empties) both the transmit and receive FIFO. Later SoCs have independent flush bits for each FIFO. Independent FIFOs can be flushed before the snd_soc_dai_active() check because it won't disturb other active streams. This ensures that the FIFO we're about to use is always flushed before starting up. With shared FIFOs we can't do that because if another substream is active, flushing its FIFO would cause underrun errors. This also fixes a bug: since we were only setting the JZ4740's flush bit, which corresponds to the TX FIFO flush bit on other SoCs, other SoCs were not having their RX FIFO flushed at all.

Pierre-Louis Bossart authored
The SOF HDAudio code stores the Host DMA hdac_stream structure in the FE substream->runtime->private_data. The BE dailink also uses the substream->runtime->private_data to allocate the link DMA stream tag. This really works by accident: the DPCM core copies the FE runtime information in the BE, which has the side-effect of sharing the FE-specific private_data with the BE. To avoid more uses of the private_data with potential issues such as accessing stale information or use-after-free cases, this patch removes most of the usages of this private_data at the BE level. We can directly use the existing dma_data to access the relevant information. However the hw_params still uses the information, mainly to go back to the 'bus' structure required for the link dma stream tag allocation. This is safe in that the 'bus' is not stream or PCM specific. The next patch will completely remove this last use of private_data by using the component_drvdata - which is how SOF passes a global context around.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: In IPC4 all DSP loadable executable is a 'library' containing modules. The main or basefw is also a library which contains multiple modules. IPC4 allows to use loadable libraries to extend the functionality of the booted basefw. This series adds support for loading external libraries in case they are needed by the loaded topology file. The libraries must be placed to a specific firmware directory (fw_lib_prefix), which is: intel/avs-lib|sof-ipc4-lib/ followed by the platform name and in case of community key use a 'community' directory. For example for upx-i11 (community key): intel/avs-lib/tgl/community is the default path. The name of the library should be the UUID of the module it contains since the library loading is going to look for the file as <module_UUID>.bin In case there is a need to bundle multiple modules into single library, symlinks can be used to point to the file: module_boundle.bin <UUID1>.bin -> module_boundle.bin <UUID2>.bin -> module_boundle.bin <UUID3>.bin -> module_boundle.bin But note that in this case all modules will be loaded to the DSP since only the whole library can be loaded, not individual modules.

In case the requested module is not available among the loaded libraries, try to load it as external library. The kernel will try to load the file from <fw_lib_prefix>/<module_uuid>.bin If the file found, then the ext manifest of it is parsed, placed it under XArray and the pointer to the module is returned to the caller. Releasing the firmware will be done on ipc cleanup time.
