* 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.
Possible compatibles:
"fsl,qoriq-device-config-1.0"
"fsl,qoriq-device-config-2.0"
"fsl,<chip>-device-config"
"fsl,<chip>-guts"
- 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).
- fsl,liodn-bits : Indicates the number of defined bits in the LIODN
registers, for those SOCs that have a PAMU device.
- little-endian : Indicates that the global utilities block is little
endian. The default is big endian.
Examples:
global-utilities@e0000 { /* global utilities block */
compatible = "fsl,mpc8548-guts";
reg = <e0000 1000>;
fsl,has-rstcr;
};
guts: global-utilities@e0000 {
compatible = "fsl,qoriq-device-config-1.0";
reg = <0xe0000 0xe00>;
fsl,has-rstcr;
#sleep-cells = <1>;
fsl,liodn-bits = <12>;
};
