The /usr/bin/power_key.py script basically does 2 things:

* set a devfreq governor once (and handle frequencies but only on old kernels)
* shut down the system when the power button is being pressed for ca. 2 seconds

The first task is to be replaced via a simple udev rule. The second one
is being tracked by OS-issues#146


and will be replaced by a GUI anyways.

This solves problems with the power_key script:
* it is not syncronised with the display system.
* it is a nightmare to maintain and keep working

In my tests, the long-press shutdown mechanism didn't work anymore, but if
it does for you, this will remove it (temporarily, see the above issue).

By moving the AUX BM818 antenna connector to the unmarked center position
the modem can get a GPS signal. This NOT the GNSS controlled by HKS but is
part of the WWAN modem so is bound to the modem firmware and the WWAN HKS.

devfreq is being handled differently on our kernels. With 5.6+ frequency
is switched automatically by the kernel for devfreq, when the powersave
governor is set. So in that case we only to that (done by udev in the future).

This also makes devfreq settings compatible with the devkit again because
it reads the minimum frequency which is different than on the phone,
from sysfs.

Also, we particularly handle 5.6-rc based kernel versions that
include a broken devfreq implementation / setup. starting with version
5.6.0 we need to increment the ABI version to 2.

Suggested by Guido. Thanks.

Linux changes the sysfs naming of devfreq from what we currently use, see

As on Linux 5.6 this is totally stable for me on Birch, I'd like to use 25Mhz
instead of 100 when the screen is off.

I ran "stress -c 2 -vm 2" while using the phone on the console and
turning on the screen, browsing the web and the system kept usable
the whole time.

With this, the device cools down more quickly when the screen is
off and improves battery time.

For Linux 5.3 (only), we keep the current behaviour as 25Mhz doesn't seem
to be stable there.

The script needs to run as root anyway

This is initially linked to /usr via the postinst but
will self destruct upon first use.

The system blanks the screen not suspend so remove the suspend labels

Wys now has a configuration database based on the machine name.  We no
longer need to have configuration files in device-specific packages.

This allows us to set the microphone volume which PulseAudio uses by
default.  The configuration is not split into codec-specific parts as
this is not necessary, the configuration's only purpose is to allow us
to set the microphone volume which PulseAudio uses and it's not clear
whether ALSA's UCM will be useful going forward.

Closes OS-issues#46

Add a systemd .conf file to extend the wys.service unit with
configuration for the devkit audio hardware.
