Adds support for simulating a mouse using GPIO lines. The driver
needs an appropriate platform device to be created by architecture
code.
The driver has been tested on AT32AP7000 microprocessor using the
ATSTK1000 development board.

Add support to wistron_btns for leds that come with the multimedia keys.
Mail and wifi leds are supported, on laptops which have them.
Depending on the laptop, wifi subsystem may control just the led, or both
the led and the wifi card. Wifi led interface is activated only for the
former type of laptops, as the latter type is already managed. Leds are
controled by the interface in /sys/class/leds.

Reduces the polling frequency from 10 Hz to 2 Hz, which should be less a burden
for laptops wrt energy saving. As it is multimedia keys, 500ms (maximum) of
latency should be still fine for the user. In order to keep fluent the feeling
when the user is pressing several keys in a raw (such as changing the volume),
the frequency is increased for a short duration after a key is pressed.

Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th
bit of the first packet (yes, it breaks the standard PS/2 protocol).
This patch adds an extra protocol to generate BTN_SIDE based on the 4th
bit. There's no way to detect those trackballs using any kind of special
sequence, thus the protocol must be activated explicitely by writing
into 'protocol' sysfs attribute:
echo -n "cortps" > /sys/devices/platform/i8042/serio1/protocol

we need only one interface protocol from four availaible. It means

Not directly related to x86, but I got tired of seeing these warnings on every

drivers/input/mouse/Kconfig:182:warning: 'select' used by config symbol 'MOUSE_ATARI' refers to undefined symbol 'ATARI_KBD_CORE'
I moved the definition of ATARI_KBD_CORE into drivers/input/keyboard/Kconfig
so it's always seen by Kconfig.

There is a race between input handler's release() and disconnect()
methods: when input handler disconnects it wakes up all regular
users and then process to walk user list to wake up async. users.
While disconnect() walks the list release() removes elements of
the same list causing oopses.
While this is not a substibute for proper locking we can reduce
odds of getting an oops if we wake up normal readers after walking
the list.

In commit [1] the SPI mode is set to 1, but it should be 0. As stated
in the commit, ads784x samples the data on the rising edge. SPI mode 1
samples on the falling edge [2] though.
The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.
