1 * Global Utilities Block
2
3 The global utilities block controls power mana
4 enabling, power-on-reset configuration monitor
5 I/O signal configuration, alternate function s
6 signals, and clock control.
7
8 Required properties:
9
10 - compatible : Should define the compatible d
11 global-utilities.
12 Possible compatibles:
13 "fsl,qoriq-device-config-1.0"
14 "fsl,qoriq-device-config-2.0"
15 "fsl,<chip>-device-config"
16 "fsl,<chip>-guts"
17 - reg : Offset and length of the register set
18
19 Recommended properties:
20
21 - fsl,has-rstcr : Indicates that the global u
22 contains a functioning "reset control regis
23 is wired to reset upon setting the HRESET_R
24
25 - fsl,liodn-bits : Indicates the number of de
26 registers, for those SOCs that have a PAMU
27
28 - little-endian : Indicates that the global u
29 endian. The default is big endian.

33 compatible = "fsl,mpc8548-guts
34 reg = <e0000 1000>;
35 fsl,has-rstcr;
36 };
37
38 guts: global-utilities@e0000 {
39 compatible = "fsl,qoriq-device
40 reg = <0xe0000 0xe00>;
41 fsl,has-rstcr;
42 #sleep-cells = <1>;
43 fsl,liodn-bits = <12>;
