Avoid commit new plane time close to vsync at async mode, the following case maybe lead to error: vsync[1]->update plane[2]->config done[3]->update plane[4]->vsync[5] If new vsync[5] insert step 4, only part of plane register complete, this will lead to part of plane register take effect and lead to error. So we introduce this safeguard, when commit time exceeds 15/16 of a frame, this frame will be postponed to the next frame.

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.
