This patch unifies speed setting for both supported tablets. Functionality
of "wacom_poke" (used only by Graphire) is now in "wacom_set_features".
Reporting speed for both tablets can be changed by somethinkg like:
echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed
Accepted values:
0 - low speed,
1 - high speed.
The way of changing reporting speed is the same for Graphire and Intuos4 WL.

That check is valid only for Wacom Graphire, as the device raports always
start with 0x03. Intuos4 WL high-speed raports begin with 0x04, so
the check would be filtering out valid reports.

This patch adds battery/ac reporting for Intuos4 WL. It uses existing

This patch doesn't change the way battery/ac is reported, but the changes are
required to facilitate battery reporting for Intuos4 WL.
wdata->battery_capacity now stores actual battery capacity as opposed to raw
value reported by wacom graphire previously. Power supply state is now stored
in a separate variable - it used to be calculated on-the-fly in
wacom_ac_get_property function. The raw value has to be stored as well to be
able to determine if it has changed.

On big-endian systems (e.g., Apple PowerBook), trying to use a
logitech wireless mouse with the Logitech Unifying Receiver does not
work with v3.2 and later kernels. The device doesn't show up in
/dev/input. Older kernels work fine.
That is because the new hid-logitech-dj driver claims the device. The
device arrival notification appears:
20 00 41 02 00 00 00 00 00 00 00 00 00 00 00
and we read the report_types bitfield (02 00 00 00) to find out what
kind of device it is. Unfortunately the driver only reads the first 8
bits and treats that value as a 32-bit little-endian number, so on a
powerpc the report type seems to be 0x02000000 and is not recognized.
Even on little-endian machines, connecting a media center remote
control (report type 00 01 00 00) with this driver loaded would
presumably fail for the same reason.
Fix both problems by using get_unaligned_le32() to read all four
bytes, which is a little clearer anyway. After this change, the
wireless mouse works on Hugo's PowerBook again.

We incorrectly parse incoming IR data. The extra byte contains the upper
bits and not the lower bits of the x/y coordinates. User-space expects
absolute position data from us so this patch does not break existing
applications. On the contrary, it extends the virtual view and fixes
garbage reports for margin areas of the virtual screen.

Everytime a HID device is opened, a new hiddev_list is allocated with
kzalloc. This requires 64KB of physically contiguous memory, which could
easily push a heavily loaded system over the edge.
Allocating the same amount of memory with vmalloc shouldn't be nearly as
demanding, so let's do that instead. The memory isn't used for DMA and
doesn't look particularly performance sensitive, so this should be safe.

When a USB device reset occurs, usbcore will refetch the device and configuration
descriptors and compare them with those retrieved before the reset to ensure
that they have not changed. For USB HID devices, this implicitly includes the
HID class descriptor (as this is fetched with the configuration descriptor).
However, the HID report descriptor is not checked again.
Whilst a change in the size of the HID report descriptor will be detected (as
this is held in the class descriptor), content changes to the report descriptor
which do not result in a change in its size will be missed. If a firmware update
were applied to a USB HID device which resulted in such a change to the report
descriptor after device reset, then this would not be picked up by usbhid.
This patch fixes this issue by allowing usbhid to check the contents of the
report descriptor after the device reset, and trigger a rebind of the device
if there is a mismatch.

In case IO cannot be started because there is a lack of bandwidth
on the bus, it makes no sense to reset the device. If IO is requested
because the device is opened, user space should be notified with
an error right away. If the lack of bandwidth arises later, for
example after resume, there's no other choice but to retry in the
hope that bandwidth will be freed.

The previous implementation introduced a randomness in the splitting
of the different touches reported by the device. This version is more
robust as we don't rely on hi->input->absbit, but on our own structure.
This also prepares hid-multitouch to better support Win8 devices.

This patch adds supports for controlling the LED 'tachometer' on
the G27 wheel, via the LED subsystem.
The 5 LEDs are arranged from right (1=grn, 2=grn, 3=yel, 4=yel, 5=red)
and 'mirrored' to the left (10 LEDs in total).

This patch fixes a possible race condition caused by the sysfs
interface being removed after the memory used by the interface
was already kfree'd.

priv drvdata
This patch adds support for custom device-specific properties which can now be
stored as private driver data and read/saved using hid_get/set_drvdata().

Set the hid drvdata prior to invoking hid_add_device() as hid_add_device()
expects this state to be set. This bug was introduced in the recent hid
changes that were made in 07d9ab4f0e52cb ("HID: hid-hyperv: Do not use
hid_parse_report() directly").

I am merging multitouch branch into device-groups so that support
for Baanto device can be adjusted accordingly to the new autoloading
patches.

All known hid-multitouch devices currently match any device group.
However, some devices present interfaces belonging to different groups,
resulting in a race between the hid-generic and hid-multitouch modules.
This patch narrows the MT device list to match only HID_GROUP_MULTITOUCH,
which solves the problem.
As an exception, the USB_DEVICE_ID_CYPRESS_TRUETOUCH panel is not
modified, in order to suppress the unwanted extra interfaces of the
device.

Move the hid drivers of the bus drivers to a common generic hid
driver, and make it a proper module. This ought to simplify device
handling moving forward.

Switch the driver over to device group handling. By adding the
HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer
match multitouch devices. By adding the HID_GROUP_MULTITOUCH entry to
the device list, hid-multitouch will match all unknown multitouch
devices, and udev will automatically load the module.
Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling
can be removed. Since all HID MT devices have HID_DG_CONTACTID, they
can be removed from the hid_have_special_driver list.
With this patch, the unknown device ids are no longer NULL, so the code
is modified to check for the generic entry instead.

Devices that do not have a special driver are handled by the generic
driver. This patch does the same thing using device groups; Instead of
forcing a particular driver, the appropriate driver is picked up by
udev. As a consequence, one can now move a device from generic to
specific handling by a simple rebind. By adding a new device id to the
generic driver, the same thing can be done in reverse.
