PTP Interrupt mask and status register differ from the global and port interrupt mechanism by two methods. One is that for global/port interrupt enabling we have to clear the bit but for ptp interrupt we have to set the bit. And other is bit12:0 is reserved in ptp interrupt registers. This forced to not use the generic implementation of global/port interrupt method routine. This patch implement the ptp interrupt mechanism to read the timestamp register for sync, pdelay_req and pdelay_resp.

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.
