Subject: [PATCH v3 0/4] Add support for jack detection to codec present in A64 SoC
Date: Sat,  2 Mar 2024 15:00:34 +0100	[thread overview]
Message-ID: <20240302140042.1990256-1-megi@xff.cz> (raw)

From: Ondrej Jirman <megi@xff.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 a rewritten and debugged version of the original
ones from Arnaud Ferraris and Samuel Holland, improved to better
handle headset button presses and with more robust plug-in/out
event debouncing, and to use set_jack API instead of sniffing
the sound card widget names, to detect the type of jack connector.

Please take a look. :)

v3:
- removed all device-tree related code
  (it's not necessary for core functionality, it only helps make the jack detect
  functionality of the codec be usable from simple-sound-card driver, and I'll
  send it spearately, because it will apparently need several more rounds
  of review)

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
