The intel_port_to_tc() call in mtl_port_to_pll_id() assumed that all
TypeC DDI ports are connected to a TypeC PHY. This is not true on BMG
where all the ports - including the PORT_TC1..4 TypeC DDI ports - are
connected to a non-TypeC PHY. For these ports intel_port_to_tc()
returns TC_PORT_NONE, which results in an incorrect port -> PLL ID
mapping. Fix this up by using the expected PORT_TC1..4 port ->
TC_PORT_1..4 tc_port mapping on BMG as well.

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.
