f906e21f3d [platforms/hwcomposer] Support for hwcomposer 1.4 and 1.5 version
Summary:
HWcomposer version 1.4 introduced setPowerMode, which replaces the
blank(). This adds support for it. There are various code paths
possible,

- If KWin is built against hwcomposer 1.3 headers, then setPowerMode
code is not compiled in, and it will use blank to turn display off.

- If KWin is built against hwcomposer 1.4 headers, it will have
setPowerMode code path compiled in. It will be used only on devices with
1.4 and 1.5 version of hwcomposer.

This is slightly insane, because Android can report hwcomposer 1.5 even
when headers are of 1.4 version..

Test Plan: Tested this on Nexus 5X which reports 1.5 version of hwcomposer

c04e764369 [platforms/hwcomposer] Reset old brightness when turning screen back on
Summary:
Now powerdevil can adjust brightness using leds subsystem, however, kwin
as well sets brightness to 0 for turning off screen and 0xff when
turning screen back on. This resets the brightness set by the powerdevil
to 100%.

As a solution now kwin listens to brightnessChanged dbus signal of
brightnesscontrol and book-keeps the changed brightness, if screen is
turned off it sets brightness to 0 and when turning screen on, it resets
to old brightness.

If powermanagement service doesn't appear on dbus by default it restores
100% brightness.

Test Plan:
Appearantly this still doesn't work as-it-is on phone, because powerdevil
doesn't emit brightnessChanged dbus signal because of bug in the driver of
backlight control, driver doesn't seem to trigger uevents for changes in
backlight. But with hack in powerdevil to emit brightnessChanged when setting
brightness, this works

2bff90976e Move backends/ to plugins/platforms/
Summary:
Source code reorganization:
The base class AbstractBackend got renamed to Platform, thus the
"backends" are "platforms" now. As they are plugins they should go
together with other KWin plugins which are nowadays in the folder
plugins.

So new location is plugins/platforms/
