* NXP PNX watchdog timer
|

|

Required properties:
|
||||
- compatible: must be "nxp,pnx4008-wdt"
|
||||
- reg: physical base address of the controller and length of memory mapped
|
||||
region.
|

|
||||
Example:
|
||||
|
||||
watchdog@4003C000 {
|
||||
compatible = "nxp,pnx4008-wdt";
|
||||
reg = <0x4003C000 0x1000>;
