VLV_PLL_DW9_BCAST is actually VLV_PCS_DW17_BCAST. The address does kinda look like it goes to the PLL block on a first glance, but broadcast is special and doesn't even exist for the PLL (only PCS and TX have it). The fact that we use a broadcast write here is a bit sketchy IMO since we're now blasting the register to all PCS splines across the whole PHY. So the PCS registers in the other channel (ie. other pipe/port) will also be written. But I guess the fact that we always write the same value should make this a nop even if the other channel is already enabled (assuming the VBIOS/GOP didn't screw up and use some other value...).

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.
