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/...
- add DT bindings
Thank you very much,
Ondřej Jirman
Arnaud Ferraris (2):
ASoC: sun50i-codec-analog: Enable jack detection on startup
