The datasheet clearly indicates that 15 fps is the maximum achievable rate with that resolution, so I guess preventing it from being set to anything faster than that it's acceptable. > > Signed-off-by: Benoit Parrot <[email protected]> > --- > drivers/media/i2c/ov5640.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/media/i2c/ov5640.c b/drivers/media/i2c/ov5640.c > index 103a4e8f88e1..d5b0be2c7a0a 100644 > --- a/drivers/media/i2c/ov5640.c > +++ b/drivers/media/i2c/ov5640.c > @@ -1613,6 +1613,11 @@ ov5640_find_mode(struct ov5640_dev *sensor, enum > ov5640_frame_rate fr, > !(mode->hact == 640 && mode->vact == 480)) > return NULL; > > + /* 2592x1944 only works at 15fps */ > + if (fr != OV5640_15_FPS && As long as 15 fps is the lower framerate declared in ov5640_framerates[] this is ok, but I would make this condition a check for "fr > OV5640_15_FPS" so that it's safe for future extensions. (And I would check for the resolution first then FPS, so you check the most unlikely condition first, but that's really a minor optimization).
