5742  * When a userspace application wants to play a video, the content follows a
5743  * standard format definition that usually specifies the FPS for that format.
5744  * The below list illustrates some video format and the expected FPS,
5745  * respectively:
5746  *
5747  * - TV/NTSC (23.976 FPS)
5748  * - Cinema (24 FPS)
5749  * - TV/PAL (25 FPS)
5750  * - TV/NTSC (29.97 FPS)
5751  * - TV/NTSC (30 FPS)
5752  * - Cinema HFR (48 FPS)
5753  * - TV/PAL (50 FPS)
5754  * - Commonly used (60 FPS)
5755  * - Multiples of 24 (48,72,96 FPS)
5756  *
5757  * The list of standards video format is not huge and can be added to the
5758  * connector modeset list beforehand. With that, userspace can leverage
5759  * FreeSync to extends the front porch in order to attain the target refresh
5760  * rate. Such a switch will happen seamlessly, without screen blanking or
5761  * reprogramming of the output in any other way. If the userspace requests a
5762  * modesetting change compatible with FreeSync modes that only differ in the
5763  * refresh rate, DC will skip the full update and avoid blink during the
5764  * transition. For example, the video player can change the modesetting from
5765  * 60Hz to 30Hz for playing TV/NTSC content when it goes full screen without
5766  * causing any display blink. This same concept can be applied to a mode
5767  * setting change.
