After doing normal PHY-B initialization on Rocket Lake, we need to manually copy some additional PHY-A register values into PHY-B registers. Note that the bspec's combo phy page doesn't specify that this workaround is restricted to specific platform steppings (and doesn't even do a very good job of specifying that RKL is the only platform this is needed on), but the RKL workaround page lists this as relevant only for A and B steppings, so I'm trusting that information for now. v2: Make rkl_combo_phy_b_init_wa() static v3: - Minimize variables in WA function. (Jose) - Fix timeout duration (usec vs msec). (Jose) - Add verification of workaround. (Jose) - Fix stepping bounds in comment.

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.
