1 * Global Utilities Block
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.
10 - compatible : Should define the compatible device type for
13 "fsl,qoriq-device-config-1.0"
14 "fsl,qoriq-device-config-2.0"
15 "fsl,<chip>-device-config"
17 - reg : Offset and length of the register set for the device.
19 Recommended properties:
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).
25 - fsl,liodn-bits : Indicates the number of defined bits in the LIODN
26 registers, for those SOCs that have a PAMU device.
28 - little-endian : Indicates that the global utilities block is little
29 endian. The default is big endian.
