This series adds asynchronous mode support to the McASP driver, which
enables independent configuration of bitclocks, frame sync, and audio
configurations between tx(playback) and rx(record). And achieves
simultaneous playback & record using different audio configurations.

It also adds two clean up patches to the McASP driver that disambiguate
and simplifies the logic which avoids the async enhancement from being
too convoluted to review and analyze.

The implementation is based on vendor documentation and patches tested in
both SK-AM62P-LP (sync mode, McASP slave) and AM62D-EVM
(async mode, McASP master, rx & tx has different TDM configs).
Testing verifies async mode functionality while maintaining backward
compatibility with the default sync mode.

it is a shame that I never had a setup where this can be tested.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
