In 1394 OHCI, the OUTPUT_LAST descriptor of Asynchronous Transmit (AT) context has timeStamp field, in which 1394 OHCI controller record the isochronous cycle when the packet was sent for the request subaction. Additionally, the trailing quadlet of Asynchronous Receive (AR) context has timeStamp field as well in which 1394 OHCI controller record the isochronous cycle when the packet arrived. The time stamps are also available for the cases to send and receive phy packet. This commit implements new events with time stamp field for user space.

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.
