Thanks for bringing support for your hardware to the mainline.
Can I ask [email protected] to be cc-ed for phone-related
changes?
How complete is the support?
In particular, what interface do you use to configure audio routing
for the modem?
Best regards,
Pavel

Good point. Done with v3.

The components enabled should work in 5.11 (there's some LCD/DSI patches
in flight (that's why i did not send the corresponding DT addition yet)
and we need to submit a DT for Evergreen (imx8mq-librem5r4).
https://git.sigxcpu.org/cgit/talks/2020-debconf-mobile/plain/talk.pdf
is a bit outdated but has some numbers starting on page 24.

https://salsa.debian.org/DebianOnMobile-team/callaudiod manages that.

Thanks for pointer :-).

Does kernel provide mixer interface for callaudiod to do its job?

callaudiod handles selecting e.g. earpiece vs. speaker by selecting the
right pulseaudio ports (it's invoked by calls (the phone call handling
application via DBus) and only relies on the codec being an alsa
device and hence handled by pulseaudio/alsa-ucm.
Wys (https://source.puri.sm/Librem5/wys) manages the routing between the
modem and codec by listening to ModemManager's state and connecting audio
source and sink (again solely via pulsaudio so again just relying on
modem and codec being alsa devices). Since the modem is not part of the
SoC on the Librem 5 it's a completely separate device.

Aha, yep, sorry -- I forgot. I was hoping to copy solution for Librem
5 to Droid 4, but that won't work, as Droid 4 is doing audio in
hardware, while Librem does it in wys.
