Introduce the p5_sgmii field to store the information for whether port 5 has got SGMII or not. Instead of reading the MT7531_TOP_SIG_SR register multiple times, the register will be read once and the value will be stored on the p5_sgmii field. This saves unnecessary reads of the register. Move the comment about MT7531AE and MT7531BE to mt7531_setup(), where the switch is identified. Get rid of mt7531_dual_sgmii_supported() now that priv->p5_sgmii stores the information. Address the code where mt7531_dual_sgmii_supported() is used. Get rid of mt7531_is_rgmii_port() which just prints the opposite of priv->p5_sgmii. Instead of calling mt7531_pll_setup() then returning, do not call it if port 5 is SGMII. Remove P5_INTF_SEL_GMAC5_SGMII. The p5_interface_select enum is supposed to represent the mode that port 5 is being used in, not the hardware information of port 5. Set p5_intf_sel to P5_INTF_SEL_GMAC5 instead, if port 5 is not dsa_is_unused_port().

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.
