Inochi Amaoto d2b57ba171 net: phy: Add helper for fixing RGMII PHY mode based on internal mac delay 
[ Upstream commit 24afd7827e ]

The "phy-mode" property of devicetree indicates whether the PCB has
delay now, which means the mac needs to modify the PHY mode based
on whether there is an internal delay in the mac.

This modification is similar for many ethernet drivers. To simplify
code, define the helper phy_fix_phy_mode_for_mac_delays(speed, mac_txid,
mac_rxid) to fix PHY mode based on whether mac adds internal delay.

README 

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.
