[PATCH v2 0/8] ASoC: Add common modules support for ACP hw block
Changes since v1: - Fixes Kconfig indent as per kernel coding style guidelines. - Updated _GPL suffix for all exported symbol. - As suggested added separate machine ops for each codecs in machine driver - Add sound card support for newer codecs
Ajit Kumar Pandey (8): ASoC: amd: Add common framework to support I2S on ACP SOC ASoC: amd: acp: Add I2S support on Renoir platform ASoC: amd: acp: Add callback for machine driver on ACP ASoC: amd: acp: Add generic machine driver support for ACP cards ASoC: amd: acp: Add legacy sound card support for Chrome audio ASoC: amd: acp: Add SOF audio support on Chrome board ASoC: amd: acp: Add support for Maxim amplifier codec ASoC: amd: acp: Add support for RT5682-VS codec

We are using legacy way of exposing dais and DMA configuration that requires separate driver modules for various ACP SOC with almost similar hw configuration. Moreover the legacy approach requires separate I2S and DMA module platform devices registration and need machine specific quirk to control various I2S endpoints. Add generic dai driver and platform driver for I2S controller on ACP hw block. This common framework can be used by various ACP platform devices that shares common specs.

Hi, I don't see anything that tells us what "ACP" is. Please add that somewhere -- either in the Kconfig file or at least in the commit description.
thanks.

ACP stands for Audio Coprocessor in AMD platforms, will update Kconfig text with that in v3 patch chain
Add I2S dai driver for Renoir platform and register with common acp framework to support non dsp I2S use case on Renoir.

We have machines with different audio endpoints configurations across various distributions. We need to support multiple sound cards for different combinations of I2S instance and codecs hw. Now we also need to support SOF-DSP endpoints based sound cards. All such card combinations slightly differs in terms of machine ops callback. This patch adds ACP generic machine driver module that exposes method to create ACP cards dai links and define new ops for audio endpoints configurations. Initially we have added dailink support for RT5682 and RT1019 codec connection with ACP I2S_SP instance. We will add newer codecs in this module to use this for all AMD's ACP block sound cards supports in future.

This option enables legacy sound card support for ACP audio.
Add one more space just before "This" to conform to kernel Kconfig style, please.
Chrome board has RT5682 codec and RT1019 amp connected to I2S SP controller on ACP hw. Also it support DMIC capture endpoints with inbuilt pdm controller on ACP hw block. Add driver module to create backend dai links for sof dsp core. We pass driver data with audio end points configuration to register sound cards and create device nodes for all audio endpoints.
