perf: Add Arm CMN-600 DT binding
Document the requirements for the CMN-600 DT binding. The internal topology is almost entirely discoverable by walking a tree of ID registers, but sadly both the starting point for that walk and the exact format of those registers are configuration-dependent and not discoverable from some sane fixed location. Oh well. Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Will Deacon <will@kernel.org>
