 1* Global Utilities Block
 2
 3The global utilities block controls power management, I/O device
 4enabling, power-on-reset configuration monitoring, general-purpose
 5I/O signal configuration, alternate function selection for multiplexed
 6signals, and clock control.
 7
 8Required properties:
 9
10 - compatible : Should define the compatible device type for
11   global-utilities.
12 - reg : Offset and length of the register set for the device.
13
14Recommended properties:
15
16 - fsl,has-rstcr : Indicates that the global utilities register set
17   contains a functioning "reset control register" (i.e. the board
18   is wired to reset upon setting the HRESET_REQ bit in this register).
19
20 - fsl,liodn-bits : Indicates the number of defined bits in the LIODN
21   registers, for those SOCs that have a PAMU device.
22
23Examples:
24	global-utilities@e0000 {	/* global utilities block */
25		compatible = "fsl,mpc8548-guts";
26		reg = <e0000 1000>;
27		fsl,has-rstcr;
28	};
29
30	guts: global-utilities@e0000 {
31		compatible = "fsl,qoriq-device-config-1.0";
32		reg = <0xe0000 0xe00>;
33		fsl,has-rstcr;
34		#sleep-cells = <1>;
35		fsl,liodn-bits = <12>;
36	};
