-* Microchip PIC32 Watchdog Timer
-
-When enabled, the watchdog peripheral can be used to reset the device if the
-WDT is not cleared periodically in software.
-
-Required properties:
-- compatible: must be "microchip,pic32mzda-wdt".
-- reg: physical base address of the controller and length of memory mapped
-  region.
-- clocks: phandle of source clk. Should be <&rootclk LPRCCLK>.
-
-Example:
-
-       watchdog@1f800800 {
-               compatible = "microchip,pic32mzda-wdt";
-               reg = <0x1f800800 0x200>;
-               clocks = <&rootclk LPRCCLK>;
-       };
