This patch adds a new driver for the beeper controlled via GPIO pin.
The driver does not depend on the architecture and is positioned as
a replacement for the specific drivers that are used for this function.

This driver adds support for slidebars found on some Lenovo IdeaPad
laptops (the slidebars work with SlideNav/Desktop Navigator under
Windows).

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004

Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.

Now works on:
IdeaPad Y550, Y550P.

May work on (testing and adding new models is needed):
Ideapad Y560, Y460, Y450, Y650,
and, probably, some others.

The PCU is a device installed in the armrest of a plane seat and
is connected to IMS Rave Entertainment System. It has a set of control
buttons (Volume Up/Down, Attendant, Lights, etc) on one side and
gamepad-like controls on the other side.

Originally the device was handled from userspace and because of that
it presents itself on USB bus as a CDC-ACM modem device that however
can not make calls. However the custom handling is not as convenient
as using standard input subsystem facilities. If it was pure input
device it would be possible to continue using userspace solution
(moving it over to uinput), but the device also has backlighted keys
which can not be supported via uinput.

The Arizona CODECs contain a haptics module providing vibration feedback
support. Implement basic support for this, providing simple start/stop and
signal magnitude control.

Since the output path for haptics is routed through the CODEC audio routing
it is modelled as a signal generator within ASoC, the haptics driver calls
DAPM to start and stop the output drivers. An appropriate output path must
be configured via ALSA to connect the haptics source to the correct output.

proximity is measured as a binary switch, i.e. an object is either

There exist tilt switches that simply report their tilt-state via
some gpios. The number and orientation of their axes can vary
depending on the switch used and the build of the device. Also two
or more one-axis switches could be combined to provide multi-dimensional
orientation.

One example of a device using such a switch is the family of Qisda
ebook readers, where the switch provides information about the
landscape / portrait orientation of the device. The example in
Documentation/input/gpio-tilt.txt documents exactly this one-axis
device.

AD7142 and AD7147 are integrated capacitance-to-digital converters
(CDCs) with on-chip environmental calibration for use in systems
requiring a novel user input method. The AD7142 and AD7147 can interface
to external capacitance sensors implementing functions such as buttons,
scrollwheels, sliders, touchpads and so on.

The chips don't restrict the specific usage. Depending on the hardware
connection, one special target board can include one or several these
components. The platform_data for the device's "struct device" holds
these information. The data-struct defined in head file descript the
hardware feature of button/scrollwheel/slider/touchpad components on
target boards, which need be filled in the arch/mach-/.

As the result, the driver is independent of boards. It gets the
components layout from the platform_data, registers related devices,
fullfills the algorithms and state machines for these components and
report related input events to up level.

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.

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.
