[PATCH v2 0/5] ASoC: qcom: Add Nord audio support

[Mohammad Rafi Shaik]

This series adds audio support for the Qualcomm Nord Ride and
RRD boards and includes the required machine driver, device tree
binding updates, and codec improvements needed for the board's
external audio codec configuration.

Nord Ride uses a PCM1681 DAC for playback and an ADAU1979 ADC for capture.
Compared to other SC8280XP based platforms, Nord Ride requires
board-specific DAI format and codec clock configuration to support
the external PCM1681 DAC and ADAU1979 ADC.

Changes in v2:
- Dropped patch 1 from v1, as the ADAU1979 codec change has already been applied.
- Moved the compatible string from the board-specific file to the SoC file, as suggested by Shawn.
- Added runtime PM support to the PCM1681 codec to manage the SCK clock sequence.
- Added TDM support to the PCM1681 codec.
- Added the required POR delay to the PCM1681 codec, as suggested by Mark Brown.
- Replaced LPASS DAI IDs with QAIF DAI IDs.
