1 * Global Utilities Block 2 3 The global utilities block controls power management, I/O device 4 enabling, power-on-reset configuration monitoring, general-purpose 5 I/O signal configuration, alternate function selection for multiplexed 6 signals, and clock control. 7 8 Required properties: 9 10 - compatible : Should define the compatible device type for 11 global-utilities. 12 Possible compatibles: 13 "fsl,qoriq-device-config-1.0" 14 "fsl,qoriq-device-config-2.0" 15 "fsl,<chip>-device-config" 16 "fsl,<chip>-guts" 17 - reg : Offset and length of the register set for the device. 18 19 Recommended properties: 20 21 - fsl,has-rstcr : Indicates that the global utilities register set 22 contains a functioning "reset control register" (i.e. the board 23 is wired to reset upon setting the HRESET_REQ bit in this register). 24 25 - fsl,liodn-bits : Indicates the number of defined bits in the LIODN 26 registers, for those SOCs that have a PAMU device. 27 28 Examples: 29 global-utilities@e0000 { /* global utilities block */ 30 compatible = "fsl,mpc8548-guts"; 31 reg = <e0000 1000>; 32 fsl,has-rstcr; 33 }; 34 35 guts: global-utilities@e0000 { 36 compatible = "fsl,qoriq-device-config-1.0"; 37 reg = <0xe0000 0xe00>; 38 fsl,has-rstcr; 39 #sleep-cells = <1>; 40 fsl,liodn-bits = <12>; 41 };
