That's interesting, does the ISP have a dedicated DRAM ?

If no other property than remote-endpoint are allowed, I'd write
endpoint:
$ref: video-interfaces.yaml#
remote-endpoint: true
additionalProperties: false
Same below.

This should be 1.

As ports are an intrinsic property of the ISP, both should be required,
but they don't have to be connected.
By the way, how do you select at runtime which CSI-2 RX the ISP gets its
image stream from ? Is it configured through registers of the ISP ?
