Add packet timestamping TS and PTP PHC clock support. For AM65x and AM64x: - IEP1 is not used - IEP0 is configured in shadow mode with 1ms cycle and shared between Linux and FW. It provides time and TS in number cycles, so special conversation in ns is required. - IEP0 shared between PRUeth ports. - IEP0 supports PPS, periodic output. - IEP0 settime() and enabling PPS required FW interraction. - RX TS provided with each packet in CPPI5 descriptor. - TX TS returned through separate ICSSG hw queues for each port. TX TS readiness is signaled by INTC IRQ. Only one packet at time can be requested for TX TS.

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.
