There are several devices in cap11xx family besides cap1106. The driver can
be made to support all of them, so let's give it more generic name.

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 patch adds a new driver for keypad for Cirrus Logic CLPS711X CPUs.
Target CPU contain keyboard interface which can scan 8 column lines,
so we can read row GPIOs to read status and determine asserted state.

The tnetv107x platform is getting removed, so the touchscreen
and keypad drivers for this platform will no longer be needed
either.

Use the key-matrix layer to interpret key scan information from the EC
and inject input based on the FDT-supplied key map. This driver registers
itself with the ChromeOS EC driver to perform communications.

The matrix-keypad FDT binding is used with a small addition to control
ghosting.

This device is a direct pipe from "hardware" to the input event subsystem,
allowing us to avoid having to route "keypad" style events through an
AT keyboard driver (gross!).

As with the other submissions this driver is cross architecture.
