[Why] While possible for userspace to create and add custom mode based off the optimized mode for the connected display which differs only in front porch timing, this patch set adds a list of common video modes in advance. The list of common video refresh rates is small, well known and the optimized mode has specific requirements to be able to enable HW frame doubling and tripling so it makes most sense to create the modes that video players will need in advance. The optimized mode matches the preferred mode resolution but has the highest refresh rate available to enable the largest front porch extension. [How] Find the optimized mode and store it on the connector so we can check it later during our optimized modeset. Prepopulate the mode list with a list of common video mades based on the optimized mode (but with a longer front porch) if the panel doesn't support a variant of the mode natively.

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.
