Subject: [PATCH] logind: add support for TPS65217 Power Button
|
||
|
|
|
||
|
|
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.
