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 This adds: - bindings - MBHC changes to support Type-C muc - Soundwire Slave driver - Code driver The USB Mux subsystem support will be submitted separalety since it's a functionally separate subsystem connected over I2C with it's own reset signal. Signed-off-by: Neil Armstrong <neil.armstrong@xxxxxxxxxx> --- Changes in v4: - Soundwire driver - Removed volatile/read-only registers from defaults list - Added a wcd939x_readable_register() with read-only + read-write registers, so cache does it's job - Added wcd939x_volatile_register() with only volatile registers - Fixed a probable but by not using devm_ from probe() otherwise it would be freed in component unbind - Fixed lifetime of the soundwire device, by setting it un forced suspend until component it bound - Used the component bind/unbind to control the runtime pm, avoiding soundwire callbacks when not bound - Added a wcd939x_swr_get_regmap() callback, because dev_get_regmap() would not work anymore without using devm in probe - Removed useless pm_runtime_mark_last_busy in resume - Codec driver - Fixed hph_mode setup, returning 0 is already set, checking against all possible values - Used CLS_H_NORMAL instead CLS_H_INVALID as it should be in the hph_mode_mux_text list - Used wcd939x_swr_get_regmap() to get TX SoundWire device device - Fixed a probable uninitialized usage of version variable in probe - Link to v3: https://lore.kernel.org/r/20231207-topic-sm8650-upstream-wcd939x-codec-v3-0-6df9585ec7c8@xxxxxxxxxx Changes in v3: - Fixed W=1 and smatch warnings reported by lkp & Dan Carpenter - Fixed dependency on CONFIG_TYPEC and added guards to not build type-c related code when disabled - Collected review on second bindings patch - Link to v2: https://lore.kernel.org/r/20231201-topic-sm8650-upstream-wcd939x-codec-v2-0-94ed814b25aa@xxxxxxxxxx Changes in v2: - Bindings: - Dropped all references to "Slave" or "Host" terminology when possible - Collected review for first patch - Added wcd9395 as fallback of wcd9390 - Fixes typos errors - MBHC: - Dropped all references to "Slave" or "Host" terminology when possible - Fixed EXPORT_SYMBOL into EXPORT_SYMBOL_GPL - Fixed typo in commit message - Soundwire Devices driver - Dropped all references to "Slave" or "Host" terminology when possible - Dropped comments and unused code - Reworked wcd939x_swr_get_current_bank() - Added comments to wcd9390_interrupt_callback() - Reworked regmap's wcd939x_readonly/volatile_register checks - Added comments explaining while bind/unbind are empty - Added comment on SDW_SLAVE_ENTRY meaning - Added more register fields defines - Style fixes - Codec driver - Dropped all references to "Slave" or "Host" terminology when possible - Added MICB_BIAS_ values enum and used them in the code - Moved zdet_param to the top - Added TLV data for ear_pa_gain and used it - Defined as much as possible every bit field used on/from register - Replaced 1/0 to true/false when writing to single bit fields - Replaced for loop on all bits with ffs(), simplified code - Simplified MICB fields handling code - Reworked and simplified wcd939x_get/set_compander and other kcontrol get/setters - Reworked and simplified MHGC impedance/zdet/qval code, dropped dead code - Added comments on wcd939x_wd_handle_irq() utility - Added comment on the interrupt handling architecture - I've not moved common code yet, I'll probably do later since it would alter wcd939x code - Link to v1: https://lore.kernel.org/r/20231123-topic-sm8650-upstream-wcd939x-codec-v1-0-21d4ad9276de@xxxxxxxxxx --- Neil Armstrong (5): ASoC: dt-bindings: qcom,wcd938x: move out common properties ASoC: dt-bindings: document WCD939x Audio Codec ASoC: codec: wcd-mbhc-v2: add support when connected behind an USB-C audio mux ASoC: codecs: Add WCD939x Soundwire devices driver ASoC: codecs: Add WCD939x Codec driver .../devicetree/bindings/sound/qcom,wcd938x.yaml | 81 +- .../bindings/sound/qcom,wcd939x-sdw.yaml | 69 + .../devicetree/bindings/sound/qcom,wcd939x.yaml | 96 + .../bindings/sound/qcom,wcd93xx-common.yaml | 95 + sound/soc/codecs/Kconfig | 19 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/wcd-clsh-v2.h | 1 + sound/soc/codecs/wcd-mbhc-v2.c | 95 +- sound/soc/codecs/wcd-mbhc-v2.h | 3 + sound/soc/codecs/wcd939x-sdw.c | 1551 ++++++++ sound/soc/codecs/wcd939x.c | 3686 ++++++++++++++++++++ sound/soc/codecs/wcd939x.h | 989 ++++++ 12 files changed, 6597 insertions(+), 95 deletions(-) --- base-commit: 07b677953b9dca02928be323e2db853511305fa9 change-id: 20231123-topic-sm8650-upstream-wcd939x-codec-c46f621b55d4 Best regards, -- Neil Armstrong <neil.armstrong@xxxxxxxxxx>
