Some HID devices, such as my Bluetooth mouse, report their battery
strength as an event. Rather than passing it through as a strange
absolute input event, this patch registers it with the power_supply
subsystem as a battery, so that the device's Battery Strength can be
reported to usermode.
The battery appears in sysfs names
/sys/class/power_supply/hid-<UNIQ>-battery, and it is a child of the
battery-containing device, so it should be clear what it's the battery of.
Unfortunately on my current Fedora 16 system, while the battery does
appear in the UI, it is listed as a Laptop Battery with 0% charge (since
it ignores the "capacity" property of the battery and instead computes
it from the "energy*" fields, which we can't supply given the limited
information contained within the HID Report).
Still, this patch is the first step.

Genera Touch told us that 0001 is their single point device
and 0003 is the multitouch one. Apparently, we made the tests
someone having a prototype, and not the final product.
They said it should be safe to do the switch.

The previous implementation of eGalax protocol was not satisfying as
we had to manually set x/y ranges as they were corrupted after reading
the report descriptor.
Indeed, the report descriptor provided a stylus input interface which
override the correct values.
This patch omits this input, thus leaving the correct value untouched,
and the MT_QUIRK_EGALAX_XYZ_FIXUP not required anymore.

usb_kbd_event() and usb_kbd_led() can be called concurrently, but they are not
synchronized. They both readwrite kbd->leds, and usb_kbd_event() originally just
checked the URB status field, while urb.h states that "It [status field] should
not be examined before the URB is returned to the completion handler."
To fix this unsynchronized behavior, this patch introduces a boolean
representing whether the URB is submitted, and a spinlock.

The wiimote provides direct access to parts of its eeprom. This implements read
support for small chunks of the eeprom. This isn't very fast but prevents the
reader from blocking the wiimote stream for too long.
Write support is not yet supported as the wiimote breaks if we overwrite its
memory. Use hidraw to reverse-engineer the eeprom before implementing write
support here.

Motion+ reports rotation gyro data which we report to userspace as ABS_RX/Y/Z
values. The device reports them either in fast or slow mode. We adjust the
values to get a linear scale so userspace does not need to know about slow and
fast mode.
The motion+ also reports whether an extension is connected to it. We keep track
of this value and reinitialize the extensions if an extension is plugged or
unplugged.

All supported extensions report data as 6 byte block. All DRMs with extension
data provide at least 6 extension bytes. Hence a generic handler for all
extension bytes is sufficient and can be called on all DRMs.
The handler distinguishes the input and passes it to the right handler. Motion+
passes data interleaved so we can have Motion+ and a regular extension enabled
simultaneously.

The wiimote supports several extensions. This adds a separate source file which
handles all extensions and can be disabled at compile-time.
The driver reacts on "plug"-events on the extension port and starts a worker
which initializes or deinitializes the extensions.
Currently, the initialization logic is not fully understood and we can only
detect and enable all extensions when all extensions are deactivated. Therefore,
we need to disable all extensions, then detect and activate them again to react
on "plug"-events.
However, deactivating extensions will generate a new "plug"-event and we will
never leave that loop. Hence, we only support extensions if they are plugged
before the wiimote is connected (or before the ext-input device is opened). In
the future we may support full extension hotplug support, but
reverse-engineering this may take a while.

The file hid-hyperv.c implements a hid compliant mouse driver for use on a
Hyper-V based system. This driver is currently in the staging area and as part
of the effort to move this driver out of staging, I had posted the driver code
for community review a few weeks ago. This current patch addresses all the
review comments I have gotten to date. All the relevant patches have already
been submitted to the staging tree as well.
As per Greg's suggestion, this patch does not get rid of the code from
the staging area. Once the mouse driver lands under the hid directory,
we will cleanup the staging directory.

HID 1.11 specification, section 5.10 tells us:
HID class devices support the ability to ignore selected fields in a
report at run- time. This is accomplished by declaring bit field in a
report that is capable of containing a range of values larger than
those actually generated by the control. If the host or the device
receives an out-of-range value then the current value for the
respective control will not be modified.
So we shouldn't be restricted to EV_ABS only.
