* 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).

|
|
|

|
|
|
- fsl,liodn-bits : Indicates the number of defined bits in the LIODN
|
|
|
|
|
registers, for those SOCs that have a PAMU device.
