+RTC support for the rtc-m48t86 driver
+
+Required properties:
+- compatible : "rtc-m48t86"
+- reg : Array of base physical addresses for the RTC control and data
+- reg-names : must have "rtc_index" and "rtc_data"
+
+Example:
+
+rtc@808 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "rtc-m48t86";
+ reg = <0x808 0x04>,
+ <0x80c 0x04>;
+ reg-names = "rtc_index", "rtc_data";
+};
