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.

It happens because the new INPUT_WINBOND_CIR driver relies on new-leds
infrastructure - but does not select it in drivers/input/misc/Kconfig.
But it selects LEDS_CLASS, which confuses a number of other drivers into
thinking that all the leds infrastructure is in place.
Fix this by selecting NEW_LEDS as well, like similar drivers do.
Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.

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.

This driver supports the application buttons on some Fujitsu Lifebook
laptops. It is based on the earlier apanel driver done by Jochen Eisenger,
but with many changes. The original driver used ioctl's and a separate
user space program (see http://apanel.sourceforge.net). This driver hooks
into the input subsystem so that the normal keys act as expected without a
daemon. In addition to buttons, the Mail Led is handled via LEDs class
device.
The driver now supports redefinable keymaps and no longer has to have a DMI
table for all Fujitsu laptops.
I thought about mixing this driver should be integrated into the Fujitsu
laptop extras driver that handles backlight, but rejected the idea because
it wasn't clear if all the Fujitsu laptops supported both.

A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.
This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.
In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together. Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.

Initial git repository build. I'm not bothering with the full history,

3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
