The recent touchpads might not have all the information regarding the characteristics through the I2C port. On some Lenovo t480s, this results in the touchpad not being detected as a clickpad, and on the Lenovo P52, this results in a failure while fetching the resolution through I2C. We need to imitate the Windows behavior: fetch the data under PS/2, and limit the querries under I2C. This patch prepares this by exporting the info from PS/2.

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.
