EV_PWR events are a special type of event used specifically for power

Device properties:
=================
Normally, userspace sets up an input device based on the data it emits,
i.e., the event types. In the case of two devices emitting the same event
types, additional information can be provided in the form of device
properties.
INPUT_PROP_DIRECT + INPUT_PROP_POINTER:
--------------------------------------
The INPUT_PROP_DIRECT property indicates that device coordinates should be
directly mapped to screen coordinates (not taking into account trivial
transformations, such as scaling, flipping and rotating). Non-direct input
devices require non-trivial transformation, such as absolute to relative
transformation for touchpads. Typical direct input devices: touchscreens,
drawing tablets; non-direct devices: touchpads, mice.
The INPUT_PROP_POINTER property indicates that the device is not transposed
on the screen and thus requires use of an on-screen pointer to trace user's
movements. Typical pointer devices: touchpads, tablets, mice; non-pointer
device: touchscreen.
If neither INPUT_PROP_DIRECT or INPUT_PROP_POINTER are set, the property is
considered undefined and the device type should be deduced in the
traditional way, using emitted event types.
INPUT_PROP_BUTTONPAD:
--------------------
For touchpads where the button is placed beneath the surface, such that
pressing down on the pad causes a button click, this property should be
set. Common in clickpad notebooks and macbooks from 2009 and onwards.
Originally, the buttonpad property was coded into the bcm5974 driver
version field under the name integrated button. For backwards
compatibility, both methods need to be checked in userspace.
INPUT_PROP_SEMI_MT:
------------------
Some touchpads, most common between 2008 and 2011, can detect the presence
of multiple contacts without resolving the individual positions; only the
number of contacts and a rectangular shape is known. For such
touchpads, the semi-mt property should be set.
Depending on the device, the rectangle may enclose all touches, like a
bounding box, or just some of them, for instance the two most recent
touches. The diversity makes the rectangle of limited use, but some
gestures can normally be extracted from it.
If INPUT_PROP_SEMI_MT is not set, the device is assumed to be a true MT
device.
