Subject: [PATCH 01/10] HID: autocentering support for Logitech G25 Racing
 Wheel

Some months ago I send patch which adds autocentering for Logitech MOMO Wheel.
Now I have access to Logitech G25 Racing Wheel and test autocentering for it. I
write patch for current kernel to support autocentering for G25 in legacy mode
(this device supports other modes, but after switching device reconnects with
ID 0xc299 and FF support comes out) and others Logitech (Driving Force,
Formula Force Ex etc) wheels with ID 046d:c294.

Subject: [PATCH 02/10] HID: Wacom Graphire Bluetooth driver

Based on the work by Andrew Zabolotny, an HID driver for the Bluetooth
Wacom tablet. This is required as it uses a slightly different
protocols from what's currently support by the drivers/input/wacom*
driver, and those only support USB.

A user-space patch is required to activate mode 2 of the Wacom tablet,
as hidp does not support hid_output_raw_report.

Subject: [PATCH 03/10] HID: force feedback support for SmartJoy PLUS PS2/USB
 adapter

This driver adds force feedback support for SmartJoy PLUS PS2/USB adapter. I
made this driver one device spesific instead of making generic 'wisegroup-ff'
because I have another Wisegroup PS2/USB adapter that doesn't work same way as
SmartJoy PLUS. If another device that is compatible pops up, this driver could
be then renamed to something more generic.

Subject: [PATCH 04/10] HID: fix hid-ff drivers so that devices work even
 without ff support

Currently, the hid-*ff force feedback drivers, which claim the blacklisted
device on a HID bus, are only compiled in if the user selects force feedback
support.

However we want the device to be supported even when the kernel is configured
without force feedback.

This patch fixes the drivers in a way that they get compiled even if force
feedback is turned off; all the force feedback support code is compiled out in
such case, and the driver works as a usual driver on HID bus, claiming and
initializing the device, making it operational without FF effects.

Added constants to hid.h for all digitizer usages (including the new multitouch
ones that are not yet in the official USB spec but are being pushed by Microsft
as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based
Computers"). Updated hid-debug.c to support the new MT input constants such as
ABS_MT_POSITION_X.

Subject: [PATCH 07/10] HID: Multitouch support for the N-Trig touchscreen

Adds support for multitouch interaction on the N-Trig touchscreen, using the
new ABS_MT_* input constants. Single touch support works as previously. This
code was tested against two versions of the N- Trig firmware: one that supports
dual pen/finger single touch, and one that supports finger multitouch but no
pen at all. Copyright notices that looked wrong were removed, as it seems that
there is only code written in 2009 by Rafin Rubin and Stephane Chatty in this
file.

Subject: [PATCH 08/10] HID: hidraw -- fix comment about accepted devices

hidraw accepts any devices, no matter if the device has
already been claimed by other HID driver (hid-input, hidraw), and
this is intended to stay. Fix up the comment to reflect reality.

Subject: [PATCH 09/10] HID: no more reinitializtion is needed in post_reset

No more reinitialization is needed in the post reset hook, remove
the FIXME comment.

While at it, clean up whitespaces in the immediate surrounding.

 mighty mouse

Bluetooth version of Apple Mighty mouse (0x05ac/0x030c) doesn't, according to
multiple reports on linux-input@, need the same quirk as the USB version of
this mouse (0x05ac/0x0304) does.
