[PATCH v3 0/9] ASoC: SOF: core/ipc4/mtl: Add support for PCM delay reporting

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

Hi,

Changes since v2:
- Use div64_u64_rem() to make the code compile and work on non 64bit architectures

Changes since v1:
- The delay calculation updated to take into account the counter wrapping on both
  ends (host and link side).

The following series adds support for the PCM delay reporting in SOF core level
and implements the needed infrastructure with IPC4 to finally enable it for MTL.

Currently this is only supported on MTL (and via IPC4), but with the
infrastructure in place it will be possible to support other platforms with
DeepBuffer.

Regards,
Peter
