+ZTE zx2967 Watchdog timer
+
+Required properties:
+
+- compatible : should be one of the following.
+ * zte,zx296718-wdt
+- reg : Specifies base physical address and size of the registers.
+- clocks : Pairs of phandle and specifier referencing the controller's clocks.
+- resets : Reference to the reset controller controlling the watchdog
+ controller.
+
+Optional properties:
+
+- timeout-sec : Contains the watchdog timeout in seconds.
+- zte,wdt-reset-sysctrl : Directs how to reset system by the watchdog.
+ if we don't want to restart system when watchdog been triggered,
+ it's not required, vice versa.
+ It should include following fields.
+ * phandle of aon-sysctrl.
+ * offset of register that be written, should be 0xb0.
+ * configure value that be written to aon-sysctrl.
+ * bit mask, corresponding bits will be affected.
+
+Example:
+
+wdt: watchdog@1465000 {
+ compatible = "zte,zx296718-wdt";
+ reg = <0x1465000 0x1000>;
