lpc18xx uses plat_dat->mac_interface, despite wanting to validate the PHY interface. Checking the DT files (arch/arm/boot/dts/nxp/lpc/), none of them specify mac-mode which means mac_interface and phy_interface will be identical. mac_interface is only used when there is some kind of MII converter between the DesignWare MAC and PHY, and describes the interface mode that the DW MAC needs to use, whereas phy_interface describes the interface mode that the PHY uses. Noting that lpc18xx only supports MII and RMII interface modes, switch this glue driver to use plat_dat->phy_interface, and to mark that the mac_interface is not used, explicitly set it to PHY_INTERFACE_MODE_NA. The latter is safe as the only user of mac_interface for this platform would be in stmmac_check_pcs_mode(), which only checks for RGMII or SGMII.

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.
