The AM64x SoC has only 8 clusters with no interrupts routed to the A53 core on the first 2 clusters. The interrupt outputs from the IP do not go through any Interrupt Routers and are hard-wired to each processor, with only couple of interrupts from each cluster reaching the A53 core. The IP is also not built with the K3 safety feature in hardware. Add the support for this IP through a new compatible.
