Mark Brown 0c1763e20c net: netsec: Ignore 'phy-mode' on SynQuacer in DT mode 
[ Upstream commit f3bb7759a9 ]

As documented in acd7aaf51b ("netsec: ignore 'phy-mode' device
property on ACPI systems") the SocioNext SynQuacer platform ships with
firmware defining the PHY mode as RGMII even though the physical
configuration of the PHY is for TX and RX delays.  Since bbc4d71d63
("net: phy: realtek: fix rtl8211e rx/tx delay config") this has caused
misconfiguration of the PHY, rendering the network unusable.

This was worked around for ACPI by ignoring the phy-mode property but
the system is also used with DT.  For DT instead if we're running on a
SynQuacer force a working PHY mode, as well as the standard EDK2
firmware with DT there are also some of these systems that use u-boot
and might not initialise the PHY if not netbooting.  Newer firmware
imagaes for at least EDK2 are available from Linaro so print a warning
when doing this.

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 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.
