+* Global Utilities Block
+
+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 block */
+ compatible = "fsl,mpc8548-guts";
+ reg = <e0000 1000>;
+ fsl,has-rstcr;
+ };
