Simple input driver support for the events reported by the
MSP430 firmware on the DM355 EVM.  Verified using the RC5
remote included with the kit; docs weren't quite right.

Some of the keycode selections might need improvement; they
can be remapped, so there's at least a runtime workaround.
(I also suspect Linux may someday merit more generic support
for RC5 based remote controls.)

These events don't distinguish key press vs release events,
so this reports both and then skips the next event if it's
identical.  The RC5 remote codes include a "toggle" bit that
can help detect autorepeated keys; but this driver doesn't
bother with those nuances.

This driver relies on the drivers/mfd/dm355evm_msp.c code
for core features, including sharing I2C access to this
firmware with GPIO, LED, and RTC support.

This patch adds an accelerated driver for Atmel AVR32 AT32AP700X
microprocessors. It uses interrupts on the channel B in the AC97
controller. Thus, offloading the work queue in the wm97xx-ts driver.

The driver has been tested with Atmel AVR32 AT32AP7000 and Wolfson
WM9712 codec.

The driver can also be easily modified to support Atmel AT91 devices, as
AT91 and AVR32 share the same AC97C module.

The use of disable_irq inside the handler for the interrupt being
disabled has always been dangerous.  disable_irq should wait for that
handler to complete before returning -> deadlock.

For some reason this wasn't actually the case until 3aa551c9 was merged
but since this time, the ads7846 driver has deadlocked the system on
first interrupt.

Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.

This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state.  This procedure works fine and has been tested as part of
another, unpublished driver for this device.

Disable the MODULE_DEVICE_TABLE() macro on parisc since the kernel
