For PCIe and DisplayPort, the phy instance represents the controller's logical lane. Wait for the instance 0 phy's PLL to lock as other instances will never lock. We do this in xpsgtr_wait_pll_lock so callers don't have to determine the correct lane themselves. The original comment is wrong about cumulative wait times. Since we are just polling a bit, all subsequent waiters will finish immediately.

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.
