Something went a bit wrong in merging f5940231a - there's a bit of repeated
text that's been introduced.

The below patch improves the documentation for the gpio-property. Stephen
Warren has a good example here:
https://github.com/swarren/linux-tegra/commit/09789801

trackpad@4b {
  compatible = "atmel,maxtouch";
  reg = <0x4b>;
  interrupt-parent = <&gpio>;
  interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
  linux,gpio-keymap = <0 0 0 BTN_LEFT>;
};

This maps BTN_LEFT to the 4th bit of the T19 message.

Provide device tree support and binding information.  Also provide support
for a new chip "pixcir_tangoc".

It's possible that the controller has an individually switchable power supply.
Therefore add support to control a supplying regulator.

As this is not always the case, the regulator is requested as optional.

This patch adds a driver for Microchips CAP1106, an I2C driven, 6-channel
capacitive touch sensor.

For now, only the capacitive buttons are supported, and no specific
settings that can be tweaked for individual channels, except for the
device-wide sensitivity gain. The defaults seem to work just fine out of
the box, so I'll leave configurable parameters for someone who's in need
of them and who can actually measure the impact. All registers are
prepared, however. Many of them are just not used for now.

The implementation does not make any attempt to be compatible to platform
data driven boards, but fully depends on CONFIG_OF.

Power management functions are also left for volounteers with the ability
to actually test them.

This adds DT support to the tsc2005 touchscreen driver. It also adds
regulator support to the driver if booted via DT.

Add common DT binding documentation for touchscreen devices and
implement input_parse_touchscreen_of_params, which parses the common
properties and configures the input device accordingly.

The method currently does not interpret the axis inversion properties,
since there is no matching flag in the generic linux input device.

This is an input driver and belongs to input not gpio.

The sun4i resisitive touchscreen controller also comes with a built-in
temperature sensor. This commit adds support for it.

This commit also introduces a new "ts-attached" device-tree property,
when this is not set, the input part of the driver won't register. This way
the internal temperature sensor can be used to measure the SoC temperature
independent of there actually being a touchscreen attached to the controller.
