Some devices with support for mobile networks may have buttons for
enabling/disabling such connection. An example can be Linksys router 54G3G.
We already have KEY_BLUETOOTH, KEY_WLAN and KEY_UWB so it makes sense to
add KEY_WWAN as well. As we already have KEY_WIMAX, use it's value for
KEY_WWAN and make it an alias.

Some devices, such as new Intuos series tablets, have a hardware switch to
turn touch data on/off. To report the state, SW_MUTE_DEVICE is added
in include/uapi/linux/input.h.

Pull input update from Dmitry Torokhov:
"The only change is David Hermann's new EVIOCREVOKE evdev ioctl that
allows safely passing file descriptors to input devices to session
processes and later being able to stop delivery of events through
these fds so that inactive sessions will no longer receive user input
that does not belong to them"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: evdev - add EVIOCREVOKE ioctl
If we have multiple sessions on a system, we normally don't want
background sessions to read input events. Otherwise, it could capture
passwords and more entered by the user on the foreground session. This is
a real world problem as the recent XMir development showed:
http://mjg59.dreamwidth.org/27327.html
We currently rely on sessions to release input devices when being
deactivated. This relies on trust across sessions. But that's not given on
usual systems. We therefore need a way to control which processes have
access to input devices.
With VTs the kernel simply routed them through the active /dev/ttyX. This
is not possible with evdev devices, though. Moreover, we want to avoid
routing input-devices through some dispatcher-daemon in userspace (which
would add some latency).
This patch introduces EVIOCREVOKE. If called on an evdev fd, this revokes
device-access irrecoverably for that *single* open-file. Hence, once you
call EVIOCREVOKE on any dup()ed fd, all fds for that open-file will be
rather useless now (but still valid compared to close()!). This allows us
to pass fds directly to session-processes from a trusted source. The
source keeps a dup()ed fd and revokes access once the session-process is
no longer active.
Compared to the EVIOCMUTE proposal, we can avoid the CAP_SYS_ADMIN
restriction now as there is no way to revive the fd again. Hence, a user
is free to call EVIOCREVOKE themself to kill the fd.
Additionally, this ioctl allows multi-layer access-control (again compared
to EVIOCMUTE which was limited to one layer via CAP_SYS_ADMIN). A middle
layer can simply request a new open-file from the layer above and pass it
to the layer below. Now each layer can call EVIOCREVOKE on the fds to
revoke access for all layers below, at the expense of one fd per layer.
There's already ongoing experimental user-space work which demonstrates
how it can be used:

"Input: introduce BTN/ABS bits for drums and guitars"
"HID: wiimote: add support for Guitar-Hero drums"
"HID: wiimote: add support for Guitar-Hero guitars"
The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic. It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.
We'll try again for 3.13.

There are a bunch of guitar and drums devices out there that all report
similar data. To avoid reporting this as BTN_MISC or ABS_MISC, we
allocate some proper namespace for them. Note that most of these devices
are toys and we cannot report any sophisticated physics via this API.
I did some google-images research and tried to provide definitions that
work with all common devices. That's why I went with 4 toms, 4 cymbals,
one bass, one hi-hat. I haven't seen other drums and I doubt that we need
any additions to that. Anyway, the naming-scheme is intentionally done in
an extensible way.
For guitars, we support 5 frets (normally aligned vertically, compared to
the real horizontal layouts), a single strum-bar with up/down directions,
an optional fret-board and a whammy-bar.
Most of the devices provide pressure values so I went with ABS_* bits. If
we ever support devices which only provide digital input, we have to
decide whether to emulate pressure data or add additional BTN_* bits.
If someone is not familiar with these devices, here are two pictures which
provide almost all introduced interfaces (or try the given keywords
with a google-image search):

SYN_* events are special and not enabled via set_bit() for devices. Hence,
they haven't been really needed, yet. However, user-space can still make
great use of that for int->string debugging helpers or alike.
Also, I haven't seen any reason not to define these, so here they are.

Until today all gamepad input drivers report their data differently. It is
nearly impossible to write applications for more than one device in a
generic way. Therefore, this patch introduces a uniform gamepad API which
will be used for all new drivers.
Instead of mapping buttons by their labels, we now map them by position.
This allows applications to work with any gamepad regardless of the labels
on the buttons. Furthermore, we standardize the ABS_* codes for analog
triggers and sticks.
For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should
be fairly obvious how to use. To avoid confusion, the action buttons now
have BTN_EAST/SOUTH/WEST/NORTH aliases.
