1* Global Utilities Block2 3The global utilities block controls power management, I/O device4enabling, power-on-reset configuration monitoring, general-purpose5I/O signal configuration, alternate function selection for multiplexed6signals, and clock control.7 8Required properties:9 10 - compatible : Should define the compatible device type for11 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 19Recommended properties:20 21 - fsl,has-rstcr : Indicates that the global utilities register set22 contains a functioning "reset control register" (i.e. the board23 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 LIODN26 registers, for those SOCs that have a PAMU device.27 28 - little-endian : Indicates that the global utilities block is little29 endian. The default is big endian.30 31Examples:32 global-utilities@e0000 { /* global utilities block */33 compatible = "fsl,mpc8548-guts";34 reg = <e0000 1000>;35 fsl,has-rstcr;36 };37 38 guts: global-utilities@e0000 {39 compatible = "fsl,qoriq-device-config-1.0";40 reg = <0xe0000 0xe00>;41 fsl,has-rstcr;42 #sleep-cells = <1>;43 fsl,liodn-bits = <12>;44 };45
