5769  * When a userspace application wants to play a video, the content follows a
5770  * standard format definition that usually specifies the FPS for that format.
5771  * The below list illustrates some video format and the expected FPS,
5772  * respectively:
5773  *
5774  * - TV/NTSC (23.976 FPS)
5775  * - Cinema (24 FPS)
5776  * - TV/PAL (25 FPS)
5777  * - TV/NTSC (29.97 FPS)
5778  * - TV/NTSC (30 FPS)
5779  * - Cinema HFR (48 FPS)
5780  * - TV/PAL (50 FPS)
5781  * - Commonly used (60 FPS)
5782  * - Multiples of 24 (48,72,96 FPS)
5783  *
5784  * The list of standards video format is not huge and can be added to the
5785  * connector modeset list beforehand. With that, userspace can leverage
5786  * FreeSync to extends the front porch in order to attain the target refresh
5787  * rate. Such a switch will happen seamlessly, without screen blanking or
5788  * reprogramming of the output in any other way. If the userspace requests a
5789  * modesetting change compatible with FreeSync modes that only differ in the
5790  * refresh rate, DC will skip the full update and avoid blink during the
5791  * transition. For example, the video player can change the modesetting from
5792  * 60Hz to 30Hz for playing TV/NTSC content when it goes full screen without
5793  * causing any display blink. This same concept can be applied to a mode
5794  * setting change.
