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 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 | 18 + 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 | 1584 +++++++++ sound/soc/codecs/wcd939x.c | 3655 ++++++++++++++++++++ sound/soc/codecs/wcd939x.h | 983 ++++++ 12 files changed, 6592 insertions(+), 95 deletions(-) --- base-commit: 07b677953b9dca02928be323e2db853511305fa9 change-id: 20231123-topic-sm8650-upstream-wcd939x-codec-c46f621b55d4 Best regards, -- Neil Armstrong <neil.armstrong@xxxxxxxxxx>
