[PATCH v2 1/8] ASoC: amd: Add common framework to support I2S on ACP SOC

[PATCH v2 1/8] ASoC: amd: Add common framework to support I2S on ACP SOC

[Ajit Kumar Pandey]

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.

[PATCH v2 4/8] ASoC: amd: acp: Add generic machine driver support for ACP cards

[Ajit Kumar Pandey]

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.

[PATCH v2 6/8] ASoC: amd: acp: Add SOF audio support on Chrome board

[Ajit Kumar Pandey]

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.

[PATCH v2 8/8] ASoC: amd: acp: Add support for RT5682-VS codec

[Ajit Kumar Pandey]

In newer variants primary codec is rt5682vs. Add support for newer
codec variants in generic machine driver module and define driver
data to register SOF sound card.

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.

Add one more space just before "This" to conform to kernel Kconfig

ACP stands for Audio Coprocessor in AMD platforms, will update
Kconfig text with that in v3 patch chain
