-ARM Dual Cluster System Configuration Block
--------------------------------------------
-
-The Dual Cluster System Configuration Block (DCSCB) provides basic
-functionality for controlling clocks, resets and configuration pins in
-the Dual Cluster System implemented by the Real-Time System Model (RTSM).
-
-Required properties:
-
-- compatible : should be "arm,rtsm,dcscb"
-
-- reg : physical base address and the size of the registers window
-
-Example:
-
-       dcscb@60000000 {
-               compatible = "arm,rtsm,dcscb";
-               reg = <0x60000000 0x1000>;
-       };
