+Required properties:
+
+- compatible : should be "alphascale,asm9260-wdt".
+- reg : Specifies base physical address and size of the registers.
+- clocks : the clocks feeding the watchdog timer. See clock-bindings.txt
+- clock-names : should be set to
+ "mod" - source for tick counter.
+ "ahb" - ahb gate.
+- resets : phandle pointing to the system reset controller with
+ line index for the watchdog.
+- reset-names : should be set to "wdt_rst".
+
+Optional properties:
+- timeout-sec : shall contain the default watchdog timeout in seconds,
+ if unset, the default timeout is 30 seconds.
+- alphascale,mode : three modes are supported
+ "hw" - hw reset (default).
+ "sw" - sw reset.
+ "debug" - no action is taken.
+
+Example:
+
+watchdog0: watchdog@80048000 {
+ compatible = "alphascale,asm9260-wdt";
+ reg = <0x80048000 0x10>;
+ clocks = <&acc CLKID_SYS_WDT>, <&acc CLKID_AHB_WDT>;
+ clock-names = "mod", "ahb";
+ interrupts = <55>;
+ resets = <&rst WDT_RESET>;
+ reset-names = "wdt_rst";
+ timeout-sec = <30>;
+ alphascale,mode = "hw";
