The driver does a lot of iteration over the RX ports with for loops. In most cases the driver will skip unused RX ports. Also, in the future patches the FPD-Link IV support will be refreshed with TI's latest init sequences which involves a lot of additional iterations over the RX ports, often only for FPD-Link IV ports. To make the iteration simpler and to make it clearer what we're iterating over (all or only-active, all or only-fpd4), add macros and support functions for iterating the RX ports. Use the macros in the driver, replacing the for loops.

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.
