+* 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).
+
+ - fsl,liodn-bits : Indicates the number of defined bits in the LIODN
+   registers, for those SOCs that have a PAMU device.
+
+Examples:
+       global-utilities@e0000 {        /* global utilities block */
+               compatible = "fsl,mpc8548-guts";
+               reg = <e0000 1000>;
+               fsl,has-rstcr;
+       };
+
+       guts: global-utilities@e0000 {
+               compatible = "fsl,qoriq-device-config-1.0";
+               reg = <0xe0000 0xe00>;
+               fsl,has-rstcr;
+               #sleep-cells = <1>;
+               fsl,liodn-bits = <12>;
+       };
