The UCB1400 driver IRQ probe code fails to find an interrupt if all
the interrupts in the range 0-31 are nonprobe-able. This patch
removes the check of the return value so interrupts above 31 can be
detected.

Tested on InHand Fingertip4 PXA270 board.

The mouse button emulation calls input device methods from an input
device. This causes funny lock nesting which is harmless as each
device has its own locks.

Give the nesting device its own lock classes so that lockdep will not
consider them the same.

As well as clarifying the fact that the driver can cope if a second
interrupt occurs before the IRQ work is scheduled this also ensures
that calls to the machine irq_enable() are balanced, making that easier
to implement.  Normally this is redundant due to the interrupt disabling
but some unusal board configurations can trigger it.

Add support for the PSIF peripheral on AVR32 AP7 devices.  It is implemented
as a serio driver and will behave like a serio 8042 device.

The driver has been tested with a Dell keyboard capable of running on 3.3
volts and a Logitech mouse on the STK1000 + STK1002 starter kit.  The Logitech
mouse was hacked by cutting the cord and using a bi-directional voltage
converter to get the required 5 volt I/O level.

For more information about the PSIF module, see the datasheet for AT32AP700X at

The commit ae91d10a inverted Y and RY
axes on xbox360 so that up is positive and down is negative.
This is wrong, as axes on game controllers have up as negative per
convention. Also, even xpad itself reports HAT0X with up as negative.

Fix that by inverting them again.

Also, according to http://bugzilla.kernel.org/show_bug.cgi?id=10337 the
original xbox controllers also have the Y and RY axes inverted.
Fix that by inverting them as well.

For devices not specifically listed in xpad.c, xpad->dpad_mapping
is initially set to MAP_DPAD_UNKNOWN. In xpad_probe() it gets changed
to either MAP_DPAD_TO_BUTTONS or MAP_DPAD_TO_AXES, depending on the
module parameter dpad_to_buttons.

However, MAP_DPAD_UNKNOWN is defined as -1, while the field is u8.
This results in actual value of 255, causing the MAP_DPAD_UNKNOWN
check in xpad_probe() to fail.
Fix that by defining MAP_DPAD_UNKNOWN as 2 instead.

Also, setting module parameter dpad_to_buttons to 1 should obviously
map dpad to buttons, while the default behaviour (0) should be to map
dpad to axes. However, dpad_to_buttons is directly assigned to
xpad->dpad_mapping, and as MAP_DPAD_TO_BUTTONS is 0, the actual
behaviour is reversed.
Fix that by negating dpad_to_buttons in assignment.
