Add 'bus-type' and 'data-lanes' define for port0. Add DP tx lane0, lane1 swing register setting array, and audio enable flag. The device which cannot pass DP tx PHY CTS caused by long PCB trace or embedded MUX, adjusting ANX7625 PHY parameters can pass the CTS test. The adjusting type include Pre-emphasis, Vp-p, Rterm(Resistor Termination) and Rsel(Driven Strength). Each lane has maximum 20 registers for these settings.

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.
