Introduce pxa27x_keypad_config() for keypad registers configuration
and remove the reg_kpc, reg_kprec from platform data structure
so that configurations of keypad registers can be centralized to a
single function.

It can also be re-used when resuming.

 1. Introduce the "struct pxa27x_keypad" structure for driver specific
    information, such as "struct clk", generated matrix key codes and
    so on

 2. Use KEY() macro to define matrix keys, instead of original 8x8 map
    this makes definition easier with keypad where keys are sparse

 3. Keep a generated array in "struct pxa27x_keypad" for fast lookup

 4. Separate the matrix scan into a dedicated function for readability
    and report only those keys whose state has been changed, instead
    of report all states

 5. Make use of KPAS to decide the faster path if only one key has been
    detected

This patch adds a very simple input power event to APM user suspend
event bridge. Its currently only works for the systems using the
emulated APM driver but could easily be extended to work with anything
with a true APM BIOS too.

This covers a standard embedded system need which is to suspend when the
user presses a suspend button. It leaves options open to system
integrators to ignore (or unload) this code and implement their own more
complex event handling system.

Its hidden behind the EMBEDDED Kconfig option since its only likely to
be of use to embedded style systems. It can be built as a module so the
"hardcoded" policy can easily be removed from the kernel at runtime if
desired too.

This driver supports the application buttons on some Fujitsu Lifebook
laptops.  It is based on the earlier apanel driver done by Jochen Eisenger,
but with many changes.  The original driver used ioctl's and a separate
user space program (see http://apanel.sourceforge.net).  This driver hooks
into the input subsystem so that the normal keys act as expected without a
daemon.  In addition to buttons, the Mail Led is handled via LEDs class
device.

The driver now supports redefinable keymaps and no longer has to have a DMI
table for all Fujitsu laptops.

I thought about mixing this driver should be integrated into the Fujitsu
laptop extras driver that handles backlight, but rejected the idea because
it wasn't clear if all the Fujitsu laptops supported both.

Fix a buffer overflow in mutli-packet handling code.  The overflow can
only happen with eGalax devices and is even there very unlikely (only
non-report packet are affected any only when truncated after the first
byte).

Also changes the mutli-packet handling code not to drop unknown packets,
but rather just drop one byte.  This allows synchronizing on report packets
in the data stream.  It's required for some egalax devices to work at all.

Also remove the pointless 'flags' member of the device struct and set the
version number to 0.6, plus some minor cleanups.

Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates.  This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server.  Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements.  It currently does this for
tablet like devices and touchpads.  This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.

This patch enables the mouse pointer to move when using the remote
console.
