In TI's J7200 SoC CPSW5G ports, each of the 4 ports can be configured as a QSGMII main or QSGMII-SUB port. This configuration is performed by phy-gmii-sel driver on invoking the phy_set_mode_ext() function. It is necessary for the QSGMII main port to be configured before any of the QSGMII-SUB interfaces are brought up. Currently, the QSGMII-SUB interfaces come up before the QSGMII main port is configured. Fix this by moving the call to phy_set_mode_ext() from am65_cpsw_nuss_ndo_slave_open() to am65_cpsw_nuss_init_slave_ports(), thereby ensuring that the QSGMII main port is configured before any of the QSGMII-SUB ports are brought up.

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.
