On Lenovo ThinkPad T14s, the fingerprint reader placed in the power button is connected via the usb_2 controller. The controller has only a USB 2.0 PHY which is then connected via a NXP PTN3222 eUSB2 repeater, which in turn is connected to the Goodix fingerprint reader. So enable all the usb_2 controller and PHY nodes, set dual-role mode to host and describe the eUSB2 repeater in order to get the fingerprint reader discovered.

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 reStructuredText 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.
