-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 = <GIC_SPI 02 IRQ_TYPE_LEVEL_HIGH>;
- cpus = <&cpu_0>, <&cpu_1>;
