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. Add all the Mailbox clusters that generate interrupts towards the A53 core as their own nodes under the cbass_main node instead of creating an almost empty parent node for the Mailbox IP and the clusters as its child nodes. All these nodes are enabled by default in the base dtsi file, but any cluster that does not define any child sub-mailbox nodes should be disabled in the corresponding board dts files.
