+BCM7038 Watchdog timer
+
+Required properties:
+
+- compatible : should be "brcm,bcm7038-wdt"
+- reg : Specifies base physical address and size of the registers.
+
+Optional properties:
+
+- clocks: The clock running the watchdog. If no clock is found the
+ driver will default to 27000000 Hz.
+
+Example:
+
+watchdog@f040a7e8 {
+ compatible = "brcm,bcm7038-wdt";
+ clocks = <&upg_fixed>;
+ reg = <0xf040a7e8 0x16>;
+};
