This quirk is used for cases when there is GPIO which detects any type of 3.5 Jack insertion and actual type of jack is defined by other GPIO. 3.5 Jack GPIO generates interrupt and MIC GPIO indicates type of Jack only if 3.5 Jack GPIO is active.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The following series will add support for IPC4 process modules as effect widgets. We can cover wide range of modules as a generic process or effect module, the patches will lay down the fundation and the generic code to handle them. At initialization time process modules can receive additional information on top of the base_cfg, which is defined as base_cfg_ext, an extension for the base configuration struct. Other parameters or blobs for these modules are sent as a separate message via LARGE_CONFIG message, which is handled by the existing bytes control support.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: Backend DAIs may support multiple audio formats. Modify pipeline setup to select a suitable configuration based on topology and frontend DAI runtime configuration. The prime use case is BT offload support where we need the abality to select different configuration on the BE side.

The modules currently supported by the SOF firmware use the base module config containing the audio format for the input/output pin 0 for initialization. But some processing modules with multiple input/output pins require the audio formats to be sent with the init instance IPC payload. Modules that require the base config extension will need to indicate this in the module information in the firmware manifest. Introduce a new struct sof_ipc4_base_module_cfg_ext which contains the pin formats for the input and output pins. This will be appended to the init instance IPC payload for modules that require it.

Backend DAIs may support multiple audio formats. Modify pipeline setup to select a suitable configuration based on topology and frontend DAI runtime configuration. For sampling rate, if one of the BE DAI configurations has a sampling rate matching that of FE DAI, configure BE DAI to this rate. For sample format, the current code hardcodes DAI copier sample format to 32bit for both playback and capture pipelines. This is not always desired, so lift the limitation and set the sample format based on topology definitions for the copiers. For capture pipelines, we want to set the BE DAI pipeline format based on topology instead of using the FE DAI format. This covers the common use-case where BE DAI outputs data at a higher sample precision and sample width is reduced later in the pipeline. Instead of hardcoding to 32bit, use the BE DAI copier output format defined in topology.

substream->runtime will be attached when substream was opened at snd_pcm_attach_substream(). When it uses DPCM, FE substream->runtime is attached, but BE substream->runtime is not. Thus, we are copying FE substream->runtime to BE. But, we are copyig FE substream->runtime to FE dpcm->runtime first (A), and copy it to BE dpcm->runtime (B), and copy it to BE substream->runtime (C). static int dpcm_fe_dai_open(...) { ... (A) fe->dpcm[stream].runtime = fe_substream->runtime; ... } static int dpcm_be_connect(...) { ... (B) be->dpcm[stream].runtime = fe->dpcm[stream].runtime; ... } int dpcm_be_dai_startup(...) { ... (C) be_substream->runtime = be->dpcm[stream].runtime; ... } It is too roundabout and troublesome. OTOH, it is directly copying fe_substream->runtime at dpcm_be_reparent() without using be->dpcm[stream].runtime. static void dpcm_be_reparent(...) { ... for_each_dpcm_fe(be, stream, dpcm) { ... => be_substream->runtime = fe_substream->runtime; break; } } This patch removes indirect copying.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The modules in IPC4 can have multiple 'pins' on their input and output and these pins can receive or output audio in different formats. Currently we assume that all pins are using the same format which is a limitation that needs to be lifted in order to support more complex components. This series will extend and rework the format handling to allow different formats on pins.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: This series will add support for bytes control and topology types. With IPC4 only the binary payload is sent to the firmware via LARGE_CONFIG message (which does similar multi-part message handling as the IPC3 control message did). The bytes payload itself is not checked by the kernel but user space expected to wrap it in sof_abi_hdr struct in order to get the target information of the binary data. The SOF firmware and sof-ctl have been updated to support blobs used in IPC4 setups.

During route setup, playback stream routes are setup by going through sink path, capture stream routes are set up by going through source path. This is not sufficient to handle loopback cases between pipelines configured with different directions, e.g. a sidetone or an amplifier feedback connected to a speaker protection module. So, add the logic to handle such routes between widgets that aren't in the list of DAPM widgets associated with the same PCM.
