ASoC: cs-amp-lib: Add KUnit test for calibration helpers

2024-03-04T20:27:35Z

Add a KUnit test for the cs-amp-lib library. This has test cases for cs_amp_get_efi_calibration_data() and cs_amp_write_cal_coeffs(). A KUNIT_STATIC_STUB_REDIRECT() has been added to cs_amp_get_efi_variable() and cs_amp_write_cal_coeff() so that the KUnit test can redirect these to test harness functions. Much of the testing involves invoking the same function with different parameters, i.e. the number of amps and the amp index within the array. This uses parameterization rather than looping. The idea is to avoid looping over configurations within one test case as that has a higher chance of having a bug that doesn't actually test all the expected cases. Having the test run exactly one configuration, and then tear-down, is less prone to accidentally skipped configurations.

ALSA: cs35l56: Apply calibration from EFI

2024-02-24T01:58:40Z

Merge series from Richard Fitzgerald : Factory calibration of the speakers stores the calibration information into an EFI variable. This set of patches adds support for applying speaker calibration data from that EFI variable. The HDA patch (#5) depends on the ASoC patches #2 and #3

ASoC: cs-amp-lib: Add helpers for factory calibration data

2024-02-23T17:21:39Z

Create a new library for code that is used by multiple Cirrus Logic amps. This initially implements extracting amp calibration data from EFI and writing it to firmware controls. During factory calibration of built-in speakers the firmware calibration constants are stored in an EFI file. The file contains an array of calibration constants for each of the speakers. cs_amp_get_calibration_data() searches for an entry matching the requested UID stamp, otherwise by array index. If the data is found in EFI the constants for that speaker are copied back to the caller. If EFI is not enabled, the cs_amp_get_calibration_data() implementation will compile to simply return -ENOENT and the linker can drop the code. The code to write calibration controls uses cs_dsp. Building of cs_dsp is not forced. Instead, the code will compile away the calls to cs_dsp if cs_dsp is not reachable. This strategy of conditional code allows cs-amp-lib to be shared by multiple drivers without forcing inclusion of other modules that might be unnecessary. The calls to efi.get_variable() and cs_dsp are in small wrapper functions. This is so that a KUNIT_STATIC_STUB_REDIRECT can be added in a future patch to redirect these calls to replacement functions for KUnit testing.

ASoC: codecs: Add support for the framer codec

2024-01-23T18:16:23Z

The framer codec interacts with a framer. It allows to use some of the framer timeslots as audio channels to transport audio data over the framer E1/T1/J1 lines. It also reports line carrier detection events through the ALSA jack detection feature.

ASoC: codecs: Add WCD939x Codec driver

2024-01-22T00:06:19Z

Add the main WCD9390/WCD9395 Audio Codec driver to support: - 4 ADC inputs for up to 5 Analog Microphones - 4 DMIC inputs for up to 8 Digital Microphones - 4 Microphone BIAS - Stereo Headphone output - Mono EAR output - MBHC engine for Headset Detection It makes usage of the generic MBHC and CLSH generic code and the USB Type-C mux and switch helpers to gather USB-C Events in order to properly setup Headset Detection mechanism when connected behind the separate USB-C Mux subsystem. WCD9390/WCD9395 supports a PCM path for Playback instead of the actually implemented PDM playback, it will be implemented later.
