I know I asked to use the default configuration here, but what I forgot was
that the flip controls affect the media bus code as well, and the media bus
code here needs to be valid for the given flipping configuration.

Could you switch to using imx319_get_format_code() here, please?

You could do this write right after powering the sensor on, couldn't you?

You need to acquire the mutex for imx319_get_format_code().

You don't need a new function to do this; just call
v4l2_ctrl_handler_free() where you need it.

Same for this one as for imx319_pdata struct --- the driver does not
support platform data, so please do not use "pdata".

Which frequency the register lists are related to? Could you add a check
for that, and return an error if the check files?
