p0_mode set to one of the supported serial mode should not prevent configuring the external SMI interface in mv88e6xxx_g2_scratch_gpio_set_smi. The current masking of the p0_mode only checks the first 2 bits. This results in switches supporting serial mode cannot setup external SMI on certain serial modes (Ex: 1000BASE-X and SGMII). Extend the mask of the p0_mode to include the reduced modes and serial modes as allowed modes for the external SMI interface.

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.
