AMD SOF based generic SoundWire machine driver
Browse files Browse the repository at this point in the history
Merge series from Vijendar Mukunda <[email protected]>:

This patch series majorly consists of below changes.
- Rename structures, macros and codec helper names used in Intel
SoundWire generic driver to make it generic.
- Move Intel SoundWire driver common structures, macros and codec
helper functions to common placeholder so that it can be used by
other platform machine driver.
- Refactor few SoundWire common codec helper functions.
- AMD SOF based generic SoundWire machine driver for ACP 6.3 variant.

This work started a couple of months ago to avoid duplication of code
that wasn't really Intel-specific in the "sof_sdw" machine driver.
The code went through multiple iterations, was tested for multiple weeks
and a couple of build issues reported by the Intel kbuild bots were
corrected.

This is the initial version of SoundWire machine driver for AMD
platforms. Additional code refactoring will be done in the next step on
the AMD side.
