+* Krait Processor Sub-system (KPSS) Application Clock Controller (ACC)
+
+The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
+There is one ACC register region per CPU within the KPSS remaped region as
+well as an alias register region that remaps accesses to the ACC associated
+with the CPU accessing the region.
+
+Required Properties:
+
+- compatible : Shall contain "qcom,kpss-acc-v1" or "qcom,kpss-acc-v2".
+- reg: Specifies the base address and size of the banked register region.
+- cpu-offset : per-cpu offset used when the device is accessed without the
+		CPU remapping facilities.
+		The offset is cpu-offset + (0x10000 * cpu-nr).
+
+Example:
+
+	clock-controller@...8000 {
+		compatible = "qcom,kpss-acc-v2";
+		reg = <0x02008000 0x1000>;
+	};
