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. - little-endian : Indicates that the global utilities block is little endian. The default is big endian. 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>; }; |
