Future proof commit. This switch have 2 CPU ports and one valid configuration is first CPU port set to sgmii and second CPU port set to rgmii-id. The current implementation detects delay only for CPU port zero set to rgmii and doesn't count any delay set in a secondary CPU port. Drop the current delay scan function and move it to the sgmii parser function to generalize and implicitly add support for secondary CPU port set to rgmii-id. Introduce new logic where delay is enabled also with internal delay binding declared and rgmii set as PHY mode. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com> Signed-off-by: David S.

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.
