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 the item for JH7110 audio board to the dt-binding of StarFive SoC-based boards. The third 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 the raspberry pie audio board.
For more information of raspberry pie audio board, you can take a look at the following webpage: https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/
The last patch should be applied after the following patchset: https://lore.kernel.org/all/20230411135558.44282-1-xingyu.wu@starfivetech.co...
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.
