[why] When first time of link training is fail, eDP would be powered down and would not be powered up for next retry link training. It causes that all of retry link linking would be fail. [how] We has extracted both power up and down sequence from enable/disable link output function before DCN32. We remov eDP power down in dcn32_disable_link_output().

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.
