Displaying multi camera (CSI Virtual Channel)

I need to connect four FullHD/HD Cameras and display all of them in the same time, synchronized and real-time. iMX8QM has two 4-lane CSI connectors and seems to be a proper solution, but I wanna know if CSI virtual channels are supported in kernel or not?
what`s your other suggestions beside iMX8QM?

Yes the i.MX8QM and i.MX8QXP can support up to 4 virtual channels. Linux kernels 5.x should support it either though we never tested this feature. Another option is Apalis iMX6.
