* 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>;
};
