[v4,17/27] media: ov5640: Change CSI-2 timings to comply with FPS

Commit Message

Jacopo Mondi Feb. 23, 2022, 2:55 p.m. UTC

Now that the frame duration can be controlled by tuning the VBLANK
duration in CSI-2 mode, fix all modes definitions to comply with the
reported FPS.

All modes run at 30 FPS except for full-resolution mode 2592x1944
which runs at 15FPS.

Tested on a 2 data lanes setup in UYVY and RGB565 modes in CSI-2 mode.
