[PATCH v1 0/6] ASoC: qcom: add AudioReach TDM backend support

[Prasad Kumpatla]

Add AudioReach support for LPASS Audio IF based TDM backends and wire it
up for the sc8280xp machine driver.

The series first adds topology-driven Audio IF source/sink handling so
the DSP interface parameters can be described by topology while runtime
media format and slot configuration still come from the machine driver.
It then adds TDM DAI operations for q6apm-lpass-dais, exposes the Audio
IF clock IDs through the q6dsp-lpass-ports binding and q6prm clock
tables, and introduces common QCOM helpers for parsing standard
dai-tdm-slot-* properties from backend CPU and codec endpoints.

Finally, sc8280xp uses the common helpers during hw_params to program
CPU and codec TDM slots, derive the backend bit clock from the active
PCM parameters, and request the CPU and codec clocks before the stream is
started.

This series depends on:
