ADV7280M PetaLinux Driver

Hi,

I want to use ADV7280M as the analog frontend in my design and have trouble getting video data in to the Zynq Ultrascale module. My device tree is as follows;

            adv7280@20 {
                compatible = "adi,adv7281-ma";
                reg = <0x20>;
                port {
                    adv7280_out: endpoint {
                        remote-endpoint = <&csiss_in>;
                    };
                };
            };

and my V4L pipeline is;

root@zcu106_vcu_trd:~# xmedia-ctl -p
Media controller API version 4.19.0

The documentation is REALLY lacking. How do I even set the analog input port? v4l-ctl util doesn't support the S_ROUTING api the driver exposes, which I found out inspecting the source code of the driver in github.com/torvals/linux repo. Can deinterlacing be enabled through the linux driver?

What I want to do eventually is, get this video encoded with the VCU this Zynq MPSoC has.
