[PATCH v3 08/23] media: atmel: atmel-isc-base: remove frameintervals VIDIOC

Eugen Hristev
2021-12-13T13:52:14Z

VIDIOC_ENUM_FRAMEINTERVALS is not recommended for a top video driver.
The frame rate is defined by the sensor subdevice, thus it can be queried
directly by anyone interested in the frame intervals.
