Linux kernel source tree
59b806d06f
We don't actually know whether we should be picking the PHY simply based on the AUX_CH/power well, or based on the VBT defined AUX_CH->DDI->PHY relationship. At the moment we are doing the former for the ANAOVRD workaround, and the latter for the ICL_LANE_ENABLE_AUX override. Windows seems to use the first approach for everything. So let's unify this to follow that same approach for both. Eventually we should try to figure out which is actually correct, or whether any of this even matters (ie. whether there are any real machines where the DDI and its AUX_CH do not match 1:1). Note that this also changes the behaviour if we do end up poking an AUX power well not associated with any port (as per VBT). Previously we would have skipped the PHY register write, but now we always write it.

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.
