* Global Utilities Block The global utilities block controls power management, I/O device enabling, power-on-reset configuration monitoring, general-purpose I/O signal configuration, alternate function selection for multiplexed signals, and clock control. Required properties: - compatible : Should define the compatible device type for global-utilities. - 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). Example: global-utilities@e0000 { /* global utilities block */ compatible = "fsl,mpc8548-guts"; reg = ; fsl,has-rstcr; };
