We were working on a demo project for zynq ultrascale+ with the MIPI CSI RX Subsystem however it got postponed indefinitely. But you can check out Adam Taylor's own demo for our Genesys ZU board, he is using it in his block design.
As for why some of our IPs are disabled when adding them to your project's IP Repository there could be multiple answers. What board is your project set to target ? I know for a fact our MIPI IPs are NOT compatible with the zynq ultrascale+ architecture so they're greyed out for me too when trying to add them to a Genesys ZU project.
Or maybe when the source files were packaged into IPs, compatibility for Kintex7 wasn't added. However, I'm pretty sure our MIPI IPs work great on Kintex7 too, we have a FMC-Pcam-Adapter demo project for the Genesys2.
What you can try is to open your Zedboard project, right-click on the IPs that are disabled elsewhere, go to Edit in IP Packager and press OK. It will open a new vivado tab, go to Compatibility and click on the "+" button and choose Add Family Explicitly....
From there you can select to add the Kintex7 (Kintex-7) family to IP compatibility, just be aware that our MIPI IPs don't work on ultrascale and ultrascale+ families.
And that should be it, also make sure to check our Genesys2 FMC-Pcam-Adapter DEMO too, it might literally be exactly what you need for your KC705 board. Here's the wiki page (don't let the un-updated photos fool you).
Check out the the FMC-Pcam-Adapter/next branches of our Zedboard's hardware and software repos and go from there.
