From: Conor Dooley <[email protected]> On a dtb dumped from the virt machine, dt-validate complains: soc: pmu: {'riscv,event-to-mhpmcounters': [[1, 1, 524281], [2, 2, 524284], [65561, 65561, 524280], [65563, 65563, 524280], [65569, 65569, 524280]], 'compatible': ['riscv,pmu']} should not be valid under {'type': 'object'} from schema $id: http://devicetree.org/schemas/simple-bus.yaml# That's pretty cryptic, but running the dtb back through dtc produces something a lot more reasonable: Warning (simple_bus_reg): /soc/pmu: missing or empty reg/ranges property
Moving the riscv,pmu node out of the soc bus solves the problem.
