+ST-Ericsson COH 901 327 Watchdog timer

+Required properties:
+- compatible: must be "stericsson,coh901327".
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: the interrupt used for the watchdog timeout warning.
+
+Example:
+
+watchdog: watchdog@c0012000 {
+ compatible = "stericsson,coh901327";
+ reg = <0xc0012000 0x1000>;
+ interrupts = <3>;
