ASoC: wm_adsp: Add kunit test for firmware file search

2026-03-10T14:52:51+00:00

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.

ASoC: cs35l56-shared: KUnit tests for onchip speaker ID gpios

2026-02-05T16:58:12+00:00

Add KUnit testing of: cs35l56_check_and_save_onchip_spkid_gpios() cs35l56_configure_onchip_spkid_pads() cs35l56_read_onchip_spkid() The test consists of: - A mock regmap that simulates the pad and pin config registers. - Parameterization of the pin list, pulls list, a simulated value for each pin and the speaker ID value that this should produce. - A self-test of the simulated pin and GPIO registers. - A test that the value returned by cs35l56_read_onchip_spkid() is correct. - A test that the pin pull-up/down are set correctly by cs35l56_configure_onchip_spkid_pads() - A test that cs35l56_configure_onchip_spkid_pads() and cs35l56_read_onchip_spkid(0 return the expected values if cs35l56_base->num_onchip_spkid_gpios == 0. - A test that cs35l56_check_and_save_onchip_spkid_gpios() saves the configuration. - A test that cs35l56_check_and_save_onchip_spkid_gpios() rejects illegal GPIO numbers. - A test that cs35l56_check_and_save_onchip_spkid_gpios() rejects illegal pull types.

ASoC: codec: Remove ak4641/pxa2xx-ac97 and convert to

2026-01-28T00:37:49+00:00

Merge series from "Peng Fan (OSS)" : The main goal is to convert drivers to use GPIO descriptors. While reading the code, I think it is time to remove ak4641 and pxa2xx-ac97 driver, more info could be found in commit log of each patch. Then only need to convert sound/arm/pxa2xx-ac97-lib.c to use GPIO descriptors. Not have hardware to test the pxa2xx ac97.

ASoC: codec: Remove ak4641

2026-01-27T12:45:54+00:00

Since commit d6df7df7ae5a0 ("ARM: pxa: remove unused board files"), there has been no in-tree user of the AK4641 codec driver. The last user (HP iPAQ hx4700) was a non-DT PXA board file that instantiated the device via I2C board data; that code was removed as part of the PXA board-file purge. The AK4641 driver was introduced ~2011 and still probes only via the I2C device-ID table ('.id_table'), without an 'of_match_table', so there are no upstream Devicetree users to retain. With no in-tree users left, remove the driver.

ASoC: rt5575: Add the codec driver for the ALC5575

2026-01-05T13:18:52+00:00

The ALC5575 integrates an audio DSP that typically loads its firmware from an external flash via its own SPI host interface. In certain hardware configurations, the firmware can alternatively be loaded through the SPI client interface. The driver provides basic mute and volume control functions. When the SPI client interface is enabled, firmware loading is handled by the SPI driver.
