| 10 | - compatible : Should define the compatible device type for |
| 11 | global-utilities. |
| 12 | - reg : Offset and length of the register set for the device. |

| 14 | Recommended properties: |
| 15 | |
| 16 | - fsl,has-rstcr : Indicates that the global utilities register set |
| 17 | contains a functioning "reset control register" (i.e. the board |

| 20 | Example: |
| 21 | global-utilities@e0000 { /* global utilities block */ |
| 22 | compatible = "fsl,mpc8548-guts"; |
| 23 | reg = <e0000 1000>; |
