162306a36Sopenharmony_ci* Global Utilities Block 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciThe global utilities block controls power management, I/O device 462306a36Sopenharmony_cienabling, power-on-reset configuration monitoring, general-purpose 562306a36Sopenharmony_ciI/O signal configuration, alternate function selection for multiplexed 662306a36Sopenharmony_cisignals, and clock control. 762306a36Sopenharmony_ci 862306a36Sopenharmony_ciRequired properties: 962306a36Sopenharmony_ci 1062306a36Sopenharmony_ci - compatible : Should define the compatible device type for 1162306a36Sopenharmony_ci global-utilities. 1262306a36Sopenharmony_ci Possible compatibles: 1362306a36Sopenharmony_ci "fsl,qoriq-device-config-1.0" 1462306a36Sopenharmony_ci "fsl,qoriq-device-config-2.0" 1562306a36Sopenharmony_ci "fsl,<chip>-device-config" 1662306a36Sopenharmony_ci "fsl,<chip>-guts" 1762306a36Sopenharmony_ci - reg : Offset and length of the register set for the device. 1862306a36Sopenharmony_ci 1962306a36Sopenharmony_ciRecommended properties: 2062306a36Sopenharmony_ci 2162306a36Sopenharmony_ci - fsl,has-rstcr : Indicates that the global utilities register set 2262306a36Sopenharmony_ci contains a functioning "reset control register" (i.e. the board 2362306a36Sopenharmony_ci is wired to reset upon setting the HRESET_REQ bit in this register). 2462306a36Sopenharmony_ci 2562306a36Sopenharmony_ci - fsl,liodn-bits : Indicates the number of defined bits in the LIODN 2662306a36Sopenharmony_ci registers, for those SOCs that have a PAMU device. 2762306a36Sopenharmony_ci 2862306a36Sopenharmony_ci - little-endian : Indicates that the global utilities block is little 2962306a36Sopenharmony_ci endian. The default is big endian. 3062306a36Sopenharmony_ci 3162306a36Sopenharmony_ciExamples: 3262306a36Sopenharmony_ci global-utilities@e0000 { /* global utilities block */ 3362306a36Sopenharmony_ci compatible = "fsl,mpc8548-guts"; 3462306a36Sopenharmony_ci reg = <e0000 1000>; 3562306a36Sopenharmony_ci fsl,has-rstcr; 3662306a36Sopenharmony_ci }; 3762306a36Sopenharmony_ci 3862306a36Sopenharmony_ci guts: global-utilities@e0000 { 3962306a36Sopenharmony_ci compatible = "fsl,qoriq-device-config-1.0"; 4062306a36Sopenharmony_ci reg = <0xe0000 0xe00>; 4162306a36Sopenharmony_ci fsl,has-rstcr; 4262306a36Sopenharmony_ci #sleep-cells = <1>; 4362306a36Sopenharmony_ci fsl,liodn-bits = <12>; 4462306a36Sopenharmony_ci }; 45
