Bindings are about hardware, not drivers. Are you sure a fallback is
appropriate here? Does the system controller expose the same features as
it does on PolarFire SoC? For example, FPGA reprogramming: the driver
creates a platform device to which the auto update driver is bound - I
don't think that that is appropriate on a pic64gx.

Thanks,
Conor.
