As of commit 916444df30 ("ptp: deprecate gettime64() in favor of
gettimex64()") (new) PTP drivers should rather implement gettimex64().
In addition, this variant provides timestamps from the system clock. The
readings have to be recorded right before and after reading the lowest bits
of the PHC timestamp.

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.
