ASoC: sophgo: add CV1800B I2S/TDM controller driver

2026-01-27T12:52:03+00:00

The actual CPU DAI controller. The driver can be used with simple-audio-card. It respects fixed clock configuration from simple-audio-card. The card driver can request direction out, this will be interpreted as mclk out, the clock which can be used in other CPU or codecs. For example I2S3 generates clock for ADC. I2S was tested in S24_32 and S16 dual channel formats. Signed-off-by: Anton D.

ASoC: Add SoC USB APIs for adding an USB backend

2025-04-11T11:02:31+00:00

Some platforms may have support for offloading USB audio devices to a dedicated audio DSP. Introduce a set of APIs that allow for management of USB sound card and PCM devices enumerated by the USB SND class driver. This allows for the ASoC components to be aware of what USB devices are available for offloading.

ASoC: ops-test: Add some basic kunit tests for soc-ops

2025-03-19T12:47:57+00:00

Add some basic kunit tests for some of the ASoC control put and get helpers. This will assist in doing some refactoring. Note that presently some tests fail, but the rest of the series will fix these up.

ASoC: SDCA: add initial module

2024-10-17T17:42:11+00:00

Add new module for SDCA (SoundWire Device Class for Audio) support. For now just add a parser to identify the SDCA revision and the function mask. Note that the SDCA definitions and related MIPI DisCo properties are defined only for ACPI platforms and extracted with _DSD helpers. There is currently no support for Device Tree in the specification, the 'depends on ACPI' reflects this design limitation. This might change in a future revision of the specification but for SDCA 1.0 ACPI is the only supported type of platform firmware. The SDCA library is defined with static inline fallbacks, which will allow for unconditional addition of SDCA support in common parts of the code. The design follows a four-step process: 1) Basic information related to Functions is extracted from MIPI DisCo tables and stored in the 'struct sdw_slave'. Devm_ based memory allocation is not allowed at this point prior to a driver probe, so we only store the function node, address and type. 2) When a codec driver probes, it will register subdevices for each Function identified in phase 1) 3) a driver will probe for each subdevice and addition parsing/memory allocation takes place at this level. devm_ based allocation is highly encouraged to make error handling manageable. 4) Before the peripheral device becomes physically attached, register access is not permitted and the regmaps are cache-only. When peripheral device is enumerated, the bus level uses the 'update_status' notification; after optional device-level initialization, the codec driver will notify each of the subdevices so that they can start interacting with the hardware. Note that the context extracted in 1) should be arguably be handled completely in the codec driver probe. That would however make it difficult to use the ACPI information for machine quirks, and e.g. select different machine driver and topologies as done for the RT712_VB handling later in the series. To make the implementation of quirks simpler, this patchset extracts a minimal amount of context (interface revision and number/type of Functions) before the codec driver probe, and stores this context in the scope of the 'struct sdw_slave'. The SDCA library can also be used in a vendor-specific driver without creating subdevices, e.g. to retrieve the 'initialization-table' values to write platform-specific values as needed.
