Support Touchpad MCU as a special of CrOS EC devices. The current Touchpad MCU is used on Eve Chromebook and used the same protocol as other CrOS EC devices. When a MCU has touchpad support (aka EC_FEATURE_TOUCHPAD), it is instantiated as a special CrOS EC device with device name 'cros_tp'. So regardless of the probing order between the actual cros_ec and cros_tp, the userspace and other kernel drivers should not confuse them.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
