The number of QSGMII main ports are specific to the device. TI's J7200 for which the QSGMII main port property is fetched from the device-tree has only one QSGMII main port. However, devices like TI's J721e support up to two QSGMII main ports. Thus, the existing methods for fetching and using the QSGMII main port are not scalable. Update the existing methods for handling the QSGMII main ports and its associated requirements to make it scalable for future devices.

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.
