Andrew Duggan 562b42d3ee Input: synaptics-rmi4 - add support for F30
RMI4 F30 supports input from clickpad buttons and controls LEDs located
on the touchpad PCB. This patch adds support of the clickpad buttons and
defers supporting LEDs for the future.

Andrew Duggan ff8f83708b Input: synaptics-rmi4 - add support for 2D sensors and F11
RMI4 currently defines two functions for reporting data for 2D sensors
(F11 and F12). This patch adds the common functionality which is shared
by devices with 2D reporting along with implementing functionality for
F11.

Andrew Duggan 2b6a321da9 Input: synaptics-rmi4 - add support for Synaptics RMI4 devices
Synaptics uses the Register Mapped Interface (RMI) protocol as a
communications interface for their devices. This driver adds the core
functionality needed to interface with RMI4 devices.

RMI devices can be connected to the host via several transport protocols
and can supports a wide variety of functionality defined by RMI functions.
Support for transport protocols and RMI functions are implemented in
individual drivers. The RMI4 core driver uses a bus architecture to
facilitate the various combinations of transport and function drivers
needed by a particular device.
