Frame Rate is not set correctly

The avt3_video_ops_s_frame_interval function clamps the frame rate using the FRAME_RATE_MIN/MAX registers. However, these values are not necessarily correct. The frame width/height/offset is not written to the sensor until a stream is started, so the frame rate min/max values are based on the previous frame size.

For example, I'm using the ALVIUM 1800 C-510m. On startup, the frame size is set to the maximum. I set the frame rate to 250 Hz, but the driver clamps the value to ~60 Hz. When I start the stream, the driver writes the 60 Hz frame rate into the sensor. If I stop the stream, set the frame rate again, and restart - I get the correct 250 Hz behavior.

Raspberry pi driver

Hi,
Do you have any knowledge if there exist a driver compatible with the Raspberry Pi 4? Or if it would be possible to build this driver for the RPi?

Any help will be greatly appreciated.
