[Why] During S4/S3 stress test it is possible to resume from S4 without calling mode set on eDP, meaning high level optimization flag is not reset. If this is followed by an S3 resume call, driver will see optimization flag is set and consume it and think backend is powered on when in fact it is not. This results in PHY being off in sequence where S4->Resume->S3->Resume->ApplyOpt->black screen. [How] Move optimization flag to stream instead of a DC flag.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
