* 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 = <e0000 1000>;
|
|
fsl,has-rstcr;
|
|
};
