bd3ce65560 Input: rotary_encoder - add support for REL_* axes
The rotary encoder driver only supports returning input events
for ABS_* axes, this adds support for REL_* axes.  The relative
axis input event is reported as -1 for each counter-clockwise
step and +1 for each clockwise step.

The ability to clamp the position of ABS_* axes between 0 and
a maximum of "steps" has also been added.

3f3e7c6e13 Input: ads7846 - fix unsafe disable_irq
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 3aa551c9b was merged
but since this time, the ads7846 driver has deadlocked the system on
first interrupt.

Convert the driver to use the handler-safe _nosync variant.

d9bdffd210 Input: add driver for S1 button of rb532
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another, unpublished driver for this device.

b0ecc73094 Input: hilkbd - fix crash when removing hilkbd module
On parisc machines, which don't have HIL, removing the hilkbd module
panics the kernel. Fix this by adding proper implementations for the
probe and remove functions to the parisc_driver structure.

A few functions were renamed to clean up the code and make it easier
readable.

Disable the MODULE_DEVICE_TABLE() macro on parisc since the kernel
module autoloader should instead prefer the hp_sdc driver which takes
care of full HIL support, including HIL mouse and HIL tablets.
