Some hardware (such as Dell laptops) signal a variety of events through
the i8042 controller, even if these don't map to keyboard events. Add
support for drivers to filter the i8042 event stream in order to respond
to these events and (if appropriate) block them from entering the input
stream.

We need to protect not only i8042 status and data register from concurrent
access from IRQ 1 and 12 but the rest of the shared state as well, so let's
move release of i8042_lock in i8042_interrupt() a little bit further down.

Relative events are only reported via secondary device therefore device

del_timer() does not wait for the timer to finish running before returning
and therefore is technically not safe. Also make sure to enable tasklet
before kicking timer that will schedule it.

The driver does not reference identification strings in DMI table and
since these strings are no longer required by DMI core we can safely
remove them and save some memory.

Keyboard handler should not attempt to traverse handler->h_list on
its own, without any locking, otherwise it races with registering
and unregistering of input handles which leads to crashes.
Introduce input_handler_for_each_handle() helper that allows safely
iterate over all handles attached to a particular handler and switch
keyboard handler to use it.

We need to read and report gpio state when we bind the driver to the
device and upon resume so that userspace has correct state of the
switches (and keys but they are less important since, even if they
are happened to be pressed, we'd expect them to be released fairly
soon).

S3C24XX touchscreen driver, originally written by Arnaud Patard and
other contributors. The driver has had substantial testing as well as
a number of tidying up passes done by Ben Dooks, as noted:
- added kernel-doc comments to most of the routines
- removed old code from pre adc framework days
- updated device probe code to use platform id list matching
- cleaned up debug, since printk() now has timestamp feature
- ensure code uses dev_() reporting macros where necessary
- remove ABS_PRESSURE reporting, tslib can be fixed
- ensure timer is removed on driver exit
- move to using dev_pmops for power management

The touchpad on Acer Aspire 5720, 5520 and some other Aspire models
(signature 0x73, 0x02, 0x50) has a button that can be rocked in 4
different directions. Make the driver to generate BTN_0..BTN_3 events
in response. The Synaptics driver by default maps BTN_0 and BTN_1 to
up and down, so there should be no visible changes with the old setup
that generated BTN_FORWARD and BTN_BACK (also mapped to up and down).
