ASoC: Add support for the Qualcomm WSA885X Stereo smart speaker amplifier

2026-07-31T23:21:06Z

Prasad Kumpatla says: The series first documents the WSA885X devicetree binding, including supplies, GPIOs, Interrupt and battery configuration. It then adds the ASoC codec driver with register programming, serial interface setup, clock handling, mute and gain control, reset handling, interrupt support, runtime TDM slot-count configuration, and stream-time power-state sequencing. validated speaker playback on Shikra and Hawi platforms.

ASoC: codecs: add Qualcomm WSA885X codec driver

2026-07-31T23:21:04Z

Add an ASoC codec driver for the Qualcomm WSA885X stereo smart speaker amplifier. The driver programs the register map, handles reset and interrupt support, exposes DAI operations for PCM/TDM playback, and provides mixer controls for usage mode, speaker volume and RX slot mask. Keep stream-time power-state sequencing in the DAI callbacks and use regmap for the control path.

ASoC: aw88399: extract shared device library

2026-07-21T18:16:04Z

Extract the device-level functions from aw88399.c into a new shared library module (aw88399-lib.c) with a shared header at include/sound/aw88399.h, following the pattern established by CS35L41 (cs35l41-lib.c / include/sound/cs35l41.h) for chips that need both ASoC and HDA drivers. The shared header at include/sound/aw88399.h contains the register definitions, bit-field masks, hardware constants, device enums, the struct aw88399 definition, and the library function declarations. The ASoC-private header at sound/soc/codecs/aw88399.h is reduced to ASoC-specific definitions (PCM formats/rates, ALSA kcontrol helpers, calibration constants) and includes the shared header. The library contains the chip initialization, firmware loading, playback start/stop sequences, and all their internal dependencies (PLL checks, DSP management, volume control, calibration, CRC verification, etc.). The ASoC codec driver retains the ALSA controls, DAPM widgets, codec probe/remove, calibration service, and I2C bus driver registration. A new Kconfig symbol SND_SOC_AW88399_LIB is introduced. SND_SOC_AW88399 (the existing ASoC codec) selects it, ensuring no change for current users. The HDA side codec driver (introduced later in this series) selects the library without pulling in the full ASoC codec module. This avoids a build-time dependency on the full ASoC driver and follows the established pattern used by CS35L41 (SND_SOC_CS35L41_LIB) for chips with both ASoC and HDA drivers. Some library functions (DSP control, volume setting, mute, calibration updates, profile management, and status helpers) are used internally by the library's start/stop sequences but are also called directly by the ASoC driver's remaining code. These are exported from the library so the ASoC module can access them. This is a pure code movement with no functional changes. The moved functions are identical to their originals in aw88399.c.

ASoC: wm_adsp: Add kunit test for firmware file search

2026-03-10T14:52:51Z

Add KUnit testing of the wm_adsp code that searches for firmware files. Also make the SND_SOC_WM_ADSP Kconfig symbol visible if KUNIT is enabled so that wm_adsp can be manually included for KUnit testing. The firmware filename is composed of several fields, some of which are optional, and there is a search algorithm to fallback from specific to generic versions of firmware for a device. This KUnit test verifies that wm_adsp is searching for the correct sequence of filenames. The are two ways of testing this, and both are used in this KUnit test. 1. Trap the calls to firmware_request_nowarn() and test that the sequence of filenames request is correct. This is the most thorough test because it proves that exactly the expected filenames are requested, in the correct order. But it doesn't fully cover regression testing. If a change to the search algorithm changes the expected sequence of requested files, the test must also be changed to expect that new sequence. If the expectation is wrong, the tests can pass (because the search order is as expected) while picking a different file in some cases from what it did before the change. 2. Test which file is picked from a simulated directory of files. This is better for regression testing because it is independent of the search algorithm. It does not need to change if the search algorithm changes. It is not testing exactly which files the algorithm searches for, only which file it eventually picks from a given set of available files. In other words, the regression test is: does it still pick the same file from the same directory of files? But it is impractical for thorough testing. It doesn't prove that exactly the correct files were searched for, unless it was to test with every possible combination of file names and directory content that could ever exist. Clearly this is impossible to implement, since the number of combations of possible valid filenames in a directory and number of files in a directory is astronomically large.
