Subject: [PATCH v2 0/3] Add PWM-DAC audio support for StarFive JH7110 RISC-V SoC

This patchset adds PWM-DAC audio support for the StarFive JH7110 SoC.
The PWM-DAC module does not require a hardware codec, but a dummy codec is
needed for the driver. The dummy spdif codec driver, which is already
upstream, is compatible with the one which JH7110 PWM-DAC needed. So we
use it as the dummy codec driver for the JH7110 PWM-DAC module.

The third patch depends on tag next-20230728 in linux-next branch.

Changes since v1:
- Rebase on tag v6.5-rc3.
- Drop patch 1 and 2.
- Drop the unneeded space and line in patch 3.
- Use the dummy spdif codec driver instead of adding a new one.
- Change "dai_link->stop_dma_first = 1" to
  "dai_link->trigger_stop = SND_SOC_TRIGGER_ORDER_LDC" in patch 4.
- Drop the unneeded "status = "okay;" in patch 5.
- Change some node names in patch 5.
