Subject: [PATCH 0/5] Input - wacom: battery enhancements and unifying hid-wacom and wacom

Hi guys,

Continuing on the Wacom cleanup, here are 5 patches.

The first two enhance the battery reporting for the Wireless receiver by
adding the status of the battery (discharging, full, charging) - inspired by
the code found in hid-wacom.c, and also by adding notifications to the power
system so that upower knows when the battery changed.

The last three are the handling of the two Wacom Bluetooth devices in wacom.ko.
Some enhancements here:
- Intuos4 now supports other tools than just the plain stylus (mouse, artpen, ...)
- one less driver for Wacom (~700 lines of code less in total)
- unifying access to LEDs/OLEDs from Bluetooth and USB devices

However, I did not backport the speed attribute and the ac power device (which
is infered by the battery status). I don't know if there are users of those two,
so I let them aside for now. Przemo, any ideas if this is actually used?

This whole code is based on top of the previous HID conversion patches.
I pushed a branch with all I have queued on the list here:
https://github.com/bentiss/linux/commits/hid-wacom-legacy-3.16-rc4

Again, given that there has been no answer on how this can be merged upstream
(Jiri? Dmitry?), I just piled those on top of the previous.
I wouldn't to resplit the input and hid specific changes if this is the choice
that is made.

Cheers,
Benjamin
