Hi Tomi,
Thank you for the patch.

I suppose the patch is for testing only, and will be regenerated once
the API is merged in the kernel, before merging it in v4l-utils. It
should then use the sync-with-kernel.sh script to pull in all kernel
header changes.

You're right. I should have mentioned that this series is not for merging.

Add support to get and set subdev routes and to get and set
configurations per stream.
Based on work from Jacopo Mondi <jacopo@jmondi.org> and
Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>.

I tried this on TI's downstream fork with your routing patches. It works
fine for setting and viewing formats and routes.
Tested-by: Pratyush Yadav <p.yadav@ti.com>
I have not gone through the code too thoroughly. A few small things I
noticed below.

calloc man page says:
If nmemb or size is 0, then calloc() returns either NULL, or a unique
pointer value that can later be successfully passed to free().
So if a subdev reports 0 routes then you could end up with a non-NULL
pointer that you should not use, other than to pass to free(). I don't
know if any implementation out there does actually return anything other
than NULL though. I suggest explicitly checking for num_routes == 0 to
avoid all this.

You are not checking for NULL here.
