Subject: Input: gameport - make gameport_register_driver() return errors

Perform actual driver registration right in gameport_register_driver()
instead of offloading it to kgameportd and return proper error code to
callers if driver registration fails.

Note that driver <-> port matching is still done by kgameportd.

Subject: Input: ati_remote2 - add loadable keymap support

Support for loadable keymaps. The driver now supports individual
keymaps for each of the five modes (AUX1-AUX4 and PC) of the
remote. To achieve this the keymap scancode is interpreted as a
combination of the mode and actual button scancode. The original
keycode patches were done by Peter Stokes <linux@dadeos.co.uk>
but I modified it quite a lot.

Subject: Input: add keycodes for remote controls/phone keypads

The new keys are separate from normal numeric keys and standard
numeric keypads. The userspace should not attempt to apply modifiers
like shift and NumLock to these so tey work properly regardless of
the language mapping used.

By passing a gpio_button_data structure to the handler instead of the
whole platform_device the search for the right button can go away.

For now this only saves a few instructions (for gpio_keys_report_event,
gpio_keys_isr and gpio_check_button one instraction each on ARM using
arm-linux-gnu-gcc 4.2.3---I assume this is similar for other arch/compiler
combinations).

Subject: Input: atkbd - expand Latitude's force release quirk to other Dells

Dell laptops fail to send key up events for several of their special
keys. There's an existing quirk in the kernel to handle this, but it's
limited to the Latitude range. This patch extends it to cover all
portable Dells.

serio_raw only binds to non-translated devices. Enable serio_raw to

commands to the device over /dev/serio_raw<n>.

Subject: Input: psmouse - add psmouse_queue_work() for ps/2 extension to make
 use of

psmouse_queue_work is passed a delayed_work struct, and queues up the work
with kpsmouse_wq.  Since we're dealing with delayed_work stuff, this
also switches resync_work to a delayed_work struct as well, and makes
use of psmouse_queue_work when doing a resync within psmouse-base.

Subject: Input: psmouse - tweak PSMOUSE_DEFINE_ATTR to support raw set
 callbacks

We want to support attr->set callbacks that may need psmouse->state to
not be updated, or may want to manually deal w/ enabling and disabling
the device.  To do that, we create __PSMOUSE_DEFINE_ATTR which enables
us to set a 'protect' argument specifying whether or not the set
callback should be protected with psmouse_disable and state setting.

Subject: Input: psmouse - add OLPC touchpad driver

This adds support for OLPC's touchpad.  It has lots of neat features,
none of which are enabled because the hardware is too buggy.  Instead,
we use it like a normal touchpad, but with a number of workarounds in
place to deal with the frequent hardware spasms.  Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

Subject: Input: ads7846 - fix cache line sharing issue

We had a report a while back that the ads7846 driver had some issues
when used with DMA-based SPI controllers (like atmel_spi) on systems
where main memory is not DMA-coherent (most non-x86 boards). Allocate
memory potentially used for DMA separately to avoid cache line issues.

Subject: Input: move map_to_7segment.h to include/linux

The map_to_7segment.h provides generic 7segment LED mappings and is
designed to be used by other drivers.  Moving it to common area will
make it more usable.  Also exporting it to userspace will help users
of sysfs interface.

Subject: Input: i8042 - add Thinkpad R31 to nomux list

Thinkpad R31 needs i8042 nomux quirk.  Stops jittery jumping mouse
and random keyboard input. Fixes kernel bug #11723.  Cherry picked
from Ubuntu who have sometimes (on-again-off-again) had a fix in
their patched kernels.
