Direction on gen9+ was to stop reading the straps and only rely on the
VBT for marking the port presence. This happened while dealing with
WaIgnoreDDIAStrap and instead of using it as a WA, it should now be the
normal flow. See commit 885d3e5b6f ("drm/i915/display: fix comment on
skl straps").
For gen 10 it's hard to say if this will work or not since I can't test
it, so leave it with the same behavior as before.
For PCH_TGP we should still rely on the VBT to make ports E and F not
available.
v2 (Ville):
- use display ver >= 9 to make it consistent with the rest of the
driver instead of checking for == 9
- also handle CNL and only initialize port F if it is
IS_CNL_WITH_PORT_F. Eventually CNL may be removed, but while it
isn't let's keep it consistent everywhere

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.
