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-20230809 in linux-next branch.

Changes since v2:
- Rebase on tag v6.5-rc6.
- Drop the component controls.
- Use dev_err_probe() instead of dev_err() in some cases.
- Add a new struct jh7110_pwmdac_cfg to save the configuration.
- Add a new function jh7110_pwmdac_init_params() to initialize the
  parameters.

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.

[1/3] ASoC: dt-bindings: Add StarFive JH7110 PWM-DAC controller

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
