Add a generic way to create jack inputs for auxiliary jack detection
drivers (e.g. via i2c, spi), which are not part of any real codec.

Create a jack (for input-events) for jack devices in the auxiliary

Add a devicetree entry, in case not all input types are required.

Add function to return the supported jack type of snd_jack_types.
This allows a generic card driver to check whether the jack
type is valid or add all supported ones.

This check is really weird, you are checking if callbacks exist at all,
which should be unnecessary as it duplicates the work oh
snd_soc_component_ functions. I would just try to call
snd_soc_component_get_jack_supported_type() directly and if it returns
-ENOTSUPP, just go to next iteration.
I guess your main problem is snd_soc_component_set_jack(), but you can
just call it with NULL jack to check if it returns -ENOTSUPP, but I
guess the overall asumption would be that if someone implements
.get_jack_supported_type, they also implemented .set_jack, so maybe it
is just unnecessary?

Yes, it works fine without it. I will remove it.

How a device can have "set_jack"? Isn't this part of code? Are you sure
you describe here hardware, not Linux driver behavior?

Same problems.
Additionally, if this is a type of aux-dev, then maybe it should be just
added as argument to aux-dev?

No new examples, integrate it into some existing one.

Sounds like Linux details. How does BSD use this property?

Hello,
Thank you! Yes this makes things much easier. I will fix it.
