Subject: [PATCH v2 0/5] Add support for jack detection to codec present in A64 SoC

From: Ondrej Jirman <megi@....cz>

This series adds support for jack detection to this codec. I used
and tested this on Pinephone. It works quite nicely. I tested it
against Android headset mic button resistor specification.

The patches are improved and debugged version of the original
ones from Arnaud Ferraris and Samuel Holland, imrpoved to better
handle headset button presses and with more robust plug-in/out
event debouncing.

Please take a look. :)

v2:
- use set_jack/get_jack_type
- get rid of some custom poking inside card internals to figure
  out what kind of jack port we should setup the codec for
- read jack-type from OF as suggested here: 
  https://elixir.bootlin.com/linux/latest/source/sound/soc/soc-component.c#L288
- add DT bindings

Thank you very much,
	Ondřej Jirman
