Currently, phy_interface for TSN controller instance is set based on its PCI Device ID. For SGMII PHY interface, phy_interface default to PHY_INTERFACE_MODE_SGMII. As C37 AN supports both SGMII and 1000BASE-X mode, we add support for 'phy-mode' ACPI _DSD for port-specific and customer platform specific customization. v3: use fwnode_get_phy_mode() as suggested by Andrew Lunn in https://patchwork.kernel.org/comment/24895330/ v2: For platform that sets 'fixed-link' using ACPI _DSD, we will unset xpcs_an_inband within stmmac. Thanks to Russell King for his comment in https://patchwork.kernel.org/comment/24890222/ v1: Thanks to Andrew Lunn's guidance in https://patchwork.kernel.org/comment/24827101/ Tested-by: Emilio Riva <emilio.riva@ericsson.com> Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.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.
