1* Global Utilities Block 2 3The global utilities block controls power management, I/O device 4enabling, power-on-reset configuration monitoring, general-purpose 5I/O signal configuration, alternate function selection for multiplexed 6signals, and clock control. 7 8Required properties: 9 10 - compatible : Should define the compatible device type for 11 global-utilities. 12 - reg : Offset and length of the register set for the device. 13 14Recommended properties: 15 16 - fsl,has-rstcr : Indicates that the global utilities register set 17 contains a functioning "reset control register" (i.e. the board 18 is wired to reset upon setting the HRESET_REQ bit in this register). 19 20 - fsl,liodn-bits : Indicates the number of defined bits in the LIODN 21 registers, for those SOCs that have a PAMU device. 22 23Examples: 24 global-utilities@e0000 { /* global utilities block */ 25 compatible = "fsl,mpc8548-guts"; 26 reg = <e0000 1000>; 27 fsl,has-rstcr; 28 }; 29 30 guts: global-utilities@e0000 { 31 compatible = "fsl,qoriq-device-config-1.0"; 32 reg = <0xe0000 0xe00>; 33 fsl,has-rstcr; 34 #sleep-cells = <1>; 35 fsl,liodn-bits = <12>; 36 }; 37
