Bug#854388: systemd: lid switch not detected on acer chromebook

[Milan P. Stanic]

Package: systemd
Version: 232-15
Severity: normal

Dear Maintainer,

   * What led up to the situation?
	 Installed Debian on the acer chromebook R13 (mediatek MT8173 SOC,
	 board called elm (oak)) armv8 with the kernel source from chromeos
	 site and built myself for that device.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	 By closing screen logind does not detect lid switch

   * What was the outcome of this action?
	 Device does not suspend

   * What outcome did you expect instead?
	 Suspend

During boot kernel recognizes that the device have lid switch, here is
the log from journalctl:
Feb 05 17:20:01 zarya kernel: of_get_named_gpiod_flags: parsed 'gpios' property of node '/gpio-keys/lid[0]' - status (0)
Feb 05 17:20:01 zarya kernel: of_get_named_gpiod_flags: parsed 'gpios' property of node '/gpio-keys/power[0]' - status (0)

Feb 05 17:20:01 zarya kernel: input: gpio-keys as /devices/gpio-keys/input/input5

but systemd-logind does not report that it is watching any of these
keys, as it does on another armv7 or amd64 where I tested lid switch.

evtest detect all these when I run it to test does kernel works, here it
is output of invoking it:
