[ Upstream commit 425f30cc843c727bc7753a0d33710d1e4a999168 ]
Existing display port phy reg property is derived from usb phy which
map display port phy pcs to wrong address which cause aux init
with wrong address and prevent both dpcd read and write from working.
Fix this problem by assigning correct pcs address to display port
phy reg property.

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.
