+
+   The global utilities block controls power management, I/O device 
+   enabling, power-on-reset configuration monitoring, general-purpose
+   I/O signal configuration, alternate function selection for multiplexed
+   signals, and clock control.
+
+   Required properties:
+
+    - compatible : Should define the compatible device type for
+      global-utilities.
+    - reg : Offset and length of the register set for the device.
+
+  Recommended properties:
+
+    - fsl,has-rstcr : Indicates that the global utilities register set
+      contains a functioning "reset control register" (i.e. the board
+      is wired to reset upon setting the HRESET_REQ bit in this register).
+
+    Example:
+
+	global-utilities@e0000 {	/* global utilities reg */
+		compatible = "fsl,mpc8548-guts";
+		reg = <e0000 1000>;
+		fsl,has-rstcr;
+	};
+
    More devices will be defined as this spec matures.
