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.

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.

If the device is not claimed by hid-input (i.e devices driver by userspace
hiddev/hidraw-based drivers, or completely detached from HID
and driver by libusb), we must not check the hid->inptus, as it
is not guaranteed to be initialized, as this is performed only for devices
handled by hid-input.

Add Product Id 0xc299 for the Logitech G25 force feedback wheel
The Logitech G25 force feedback wheel, is first recognize by the kernel
with the product id "0xc294". In this mode, we can't use all the axes
and buttons of the wheel.
Using a userland utility, it is possible to make the wheel switch to native
mode -- http://svn.vdrift.net/viewvc.cgi/trunk/tools/G25manage/?root=VDrift
In native mode, the wheel change its id number to "0xc299".
The packet that needs to be sent to the wheel to swtich to native mode and
change its PID is
{ 0xf8, 0x10, 0x00, 0x00, 0x00, 0x00, 0x00 }

This removal was scheduled and there is no problem with later
distros to adapt for the new bus, thanks to aliases.
module-init-tools map files are deprecated nowadays, so that
the patch which introduced hid ones into the m-i-t won't be
accepted and hence there is no reason for leaving compat stuff in.

This device sends several buttons in a separate field, which is
wrongly described in the report descriptor. Fix it in the following
way:
- change led usage page to button
- report size 8 count 1 becomes report size 1 count 8
- the button usage range changed to 4-7 (the mouse has three buttons in
a different field already).

New USB device ids and quirks for the "mini" Apple USB aluminum
keyboards released Tuesday, model A1242. Note that while I own the ANSI
(0x021d) version and cannot verify that the ISO (0x021e) and JIS
(0x021f) versions exist, previous releases have followed the triple id
convention for awhile now, and the device ids fit perfectly between
USB_DEVICE_ID_APPLE_GEYSER4_* and USB_DEVICE_ID_APPLE_ALU_*.

This uses the USB busy mechanism for aggessive autosuspend of USB
HID devices. It autosuspends all opened devices supporting remote wakeup
after a timeout unless
- output is being done to the device
- a key is being held down (remote wakeup isn't triggered upon key release)
- LED(s) are lit
- hiddev is opened
As in the current driver closed devices will be autosuspended even if they
don't support remote wakeup.
The patch is quite large because output to devices is done in hard interrupt
context meaning a lot a queuing and locking had to be touched. The LED stuff
has been solved by means of a simple counter. Additions to the generic HID code
could be avoided. In addition it now covers hidraw. It contains an embryonic
version of an API to let the generic HID code tell the lower levels which
capabilities with respect to power management are needed.

The devices handled by hid-tmff and hid-zpff were added in the
hid_ignore_list[] instead of hid_blacklist[] in hid-core.c, thus
disabling them completely.
hid_ignore_list[] causes hid layer to skip the device, while
hid_blacklist[] indicates there is a specific driver in hid bus.
Re-enable the devices by moving them to the correct list.

For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes. The
beasts does not work as HID devices, even if claims to do so. cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.
The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs. In any way, it's wrong to have two completely
different modules for one device in kernel.
Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.

Now, one can test a driver e.g. by:

echo 0003 045E 00F0 > new_id
from some driver subdir.

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

This patch (as1146c) makes usbhid automatically call usbhid_set_leds()
for any device that supports the keyboard boot protocol.
In theory this should be perfectly safe. BIOSes send the LED output
report as part of their normal device initialization, so any keyboard
device supporting the boot protocol has to be able to handle it.
As a side effect, the hid-dell and hid-bright drivers are no longer
needed, and the Logitech keyboard driver can be removed from hid-lg.

While parsing 'hid_blacklist' in the apple alu wireless keyboard is not found.
This happens because in the blacklist it is declared with HID_USB_DEVICE

This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter
to the hid-dell driver. (The device shows up with a Product string
saying "Generic USB K/B", nothing more.) This will force an initial
"Set-LEDs" report to be sent to the device, without which it won't
send any keystroke information. Several bug reports mentioning this
device have been filed in various forums; the patch should resolve
them.
This is just a temporary stop-gap for 2.6.28. A later patch for
2.6.29 will introduce a more generic mechanism for "Set-LEDs", making
this change (and the entire hid-dell driver) unnecessary.

This reverts commit 740f370dc61dc478d891d7d47660bb3ae39ddb4f.
It turned out to be correct in the first place: a positive value should
be sent when the wheel is moved to the right, and a negative value when
moved to the left. This is the behavior expected by the Xorg evdev
driver. I must have had a remapping somewhere else in my system when
originally testing this. Testing on another system shows that the
unpatched kernel is correct.
