[Why] When boot into OS, seamless boot device won't blank stream. Driver update dpp clock when scanline position in vactive will show garbage on screen. [How] Wait for vblank for seamless boot edp display when driver update dpp clock. The apply seamless boot flag will be clear when OS call SetVisibility on. Therefore we only wait for vblank once after boot into OS.

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.
