When CONFIG_PTP_1588_CLOCK is compiled as a module, then the linking of
the lan966x fails because it can't find references to the following
functions 'ptp_clock_index', 'ptp_clock_register' and
'ptp_clock_unregister'
The fix consists in adding CONFIG_PTP_1588_CLOCK_OPTIONAL as a
dependency for the driver.

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.
