| * 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. |
| Possible compatibles: |
| "fsl,qoriq-device-config-1.0" |
| "fsl,qoriq-device-config-2.0" |
| "fsl,<chip>-device-config" |
| "fsl,<chip>-guts" |
| - 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>; |
| }; |
