+* ARM DynamIQ Shared Unit (DSU) Performance Monitor Unit (PMU)
+
+ARM DyanmIQ Shared Unit (DSU) integrates one or more CPU cores
+with a shared L3 memory system, control logic and external interfaces to
+form a multicore cluster. The PMU enables to gather various statistics on
+the operations of the DSU. The PMU provides independent 32bit counters that
+can count any of the supported events, along with a 64bit cycle counter.
+The PMU is accessed via CPU system registers and has no MMIO component.
+
+** DSU PMU required properties:
+
+- compatible   : should be one of :
+
+   "arm,dsu-pmu"
+
+- interrupts   : Exactly 1 SPI must be listed.
+
+- cpus : List of phandles for the CPUs connected to this DSU instance.
+
+
+** Example:
+
+dsu-pmu-0 {
+   compatible = "arm,dsu-pmu";
+   interrupts = ;
+   cpus = <_0>, <_1>;
