This patchset adds support for the audio subsystem found on Amlogic's axg SoC family. The first SoC of this family is the A113D/X targeted at smart speaker application. The G12a SoC family, Amlogic next-gen STB chipset, will reuse this audio subsystem with a few changes.
This patchset implements the DPCM machine driver and the different components it made of. Several components are still missing, such spdif input and pdm, and will submitted later on.
The fancier part of this patchset is probably around the TDM. Properly modeling the SoC architecture and its capatilities made things a little more complex than usual (details in the related commit descriptions)
If necessary, this patchset could broken into smaller series. For the intial submission, I wanted to give a global view of the subsystem. Hopefully, it will make it a bit easier to understand.
