Enable both touchpad nodes in the devictree and let the HID driver determine which one is actually populated (by attempting to read from each i2c address). Ideally this would not be needed and the boot firmware should instead enable only the node for the populated touchpad, but this is unlikely to ever be realised for the X13s. Note that the pin configuration must currently be moved to the parent i2c-bus node even though only one of these nodes will ever be successfully probed on a specific device (e.g. to allow them to be probed in parallel).

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.
