If the input masking kernel patch David did won't get applied anytime
soon it might be worth moving these tags to the hwdb, so that we don't
have to list tons of devices explicitly here.

[systemd-devel] [PATCH 1/2] logind: add support for TPS65217 Power Button

2014-09-27 Thread Koen Kooi 
This PMIC is found on TI AM335x based boards like the beaglebone and
beaglebone black.

root@beaglebone-white:~# udevadm info -a /dev/input/event0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
