[PATCH v3 0/3] Add TDM audio on StarFive JH7110

[Walker Chen]

This patchset adds TDM audio driver for the StarFive JH7110 SoC. The
first patch adds device tree binding for TDM module. The second patch
adds tdm driver support for JH7110 SoC. The last patch adds device node
of tdm and sound card to JH7110 dts.

The series has been tested on the VisionFive 2 board by plugging an
audio expansion board. 

For more information of audio expansion board, you can take a look
at the following webpage:
https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/

Changes since v2:
- Use dt-overlay to describe sound card because need to plug the audio
  expansion board into the VisionFive2 board.
- Modified the coding style for driver.
- Moved assignment of stop_dma_first to startup function of dai_driver.
- Dropped some useless macro definition.
- Use loops to get/enable/disable clocks. 

Changes since v1:
- Rebased on Linux 6.3-rc4.
- Added the dts file dedicated to describe audio card.
- Added the item for JH7110 audio board to the dt-binding of StarFive
  SoC-based boards.
