* Qualcomm Atheros AR7130 Watchdog Timer (WDT) Controller



Required properties:

- compatible: must be "qca,ar7130-wdt"

- reg: physical base address of the controller and length of memory mapped

  region.



Example:



wdt@18060008 {

	compatible = "qca,ar9330-wdt", "qca,ar7130-wdt";

	reg = <0x18060008 0x8>;
