[PATCH] ASoC: sun8i-codec: Fix build with CONFIG_SND_JACK_INPUT_DEV disabled

[Ondřej Jirman]

From: Ondrej Jirman <megi@xff.cz>

When CONFIG_SND_JACK_INPUT_DEV is disabled, struct snd_jack doesn't
have 'type' field. We can't rely on this field being always present,
so store the jack_type in the codec driver itself.

It's going to be set in probe function, once generic DT bindings for jack-type
are figured out. This is mentioned in the v3 cover letter for
https://lore.kernel.org/lkml/20240302140042.1990256-1-megi@xff.cz/

I plan on sending support for generic property mentioned here
https://elixir.bootlin.com/linux/latest/source/sound/soc/soc-component.c#L288
but it may need several iterations, and fail to get merged for various reasons
and I may need to fall back to vendor DT property, then.

If you want to test/use the jack detection on some A64 board now, what's needed
to enable this is to add:

  scodec->jack_type = SND_JACK_HEADSET | SUN8I_CODEC_BUTTONS;

  (or just SND_JACK_HEADPHONE, depednding on jack type)

to probe function and add get_jack_type callback to sun8i_soc_component:

  static int sun8i_codec_component_get_jack_type(struct snd_soc_component *component)
  {
	struct sun8i_codec *scodec = snd_soc_component_get_drvdata(component);

	return scodec->jack_type;
  }

Then detection will get enabled on A64 SoC based boards that use simple-audio-card.
(if codec is in simple-audio-card,aux-devs)

Simple card iterates through aux devices and adds jacks for the ones that return
something from component's get_jack_type() callback:

   https://elixir.bootlin.com/linux/latest/source/sound/soc/generic/simple-card-utils.c#L822

It's going to be set in probe function, once generic DT bindings for jack-type
are figured out. This is mentioned in the v3 cover letter for
https://lore.kernel.org/lkml/20240302140042.1990256-1-megi@xff.cz/

I plan on sending support for generic property mentioned here
https://elixir.bootlin.com/linux/latest/source/sound/soc/soc-component.c#L288
but it may need several iterations, and fail to get merged for various reasons
and I may need to fall back to vendor DT property, then.

If you want to test/use the jack detection on some A64 board now, what's needed
to enable this is to add:

  scodec->jack_type = SND_JACK_HEADSET | SUN8I_CODEC_BUTTONS;

  (or just SND_JACK_HEADPHONE, depednding on jack type)

to probe function and add get_jack_type callback to sun8i_soc_component:

  static int sun8i_codec_component_get_jack_type(struct snd_soc_component *component)
  {
	struct sun8i_codec *scodec = snd_soc_component_get_drvdata(component);

	return scodec->jack_type;
  }

Then detection will get enabled on A64 SoC based boards that use simple-audio-card.
(if codec is in simple-audio-card,aux-devs)

Simple card iterates through aux devices and adds jacks for the ones that return
something from component's get_jack_type() callback:

   https://elixir.bootlin.com/linux/latest/source/sound/soc/generic/simple-card-utils.c#L822

Thanks!

[1/1] ASoC: sun8i-codec: Fix build with CONFIG_SND_JACK_INPUT_DEV disabled
      commit: 559aebe45a054a479fdbd2a3dfba999ffd73cc9d

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
