+* Dallas DS1341		I2C Serial Real-Time Clock
+
+Required properties:
+
+- compatible: Should contain "dallas,ds1341".
+
+- reg: I2C address for chip
+
+Optional properties:
+
+- dallas,disable-oscillator-stop-flag : Boolean. Configure chip to disable oscillator
+  fault detection circuitry. Setting this flag is beneficial for power saving.
+
+- dallas,enable-glitch-filter : Boolean. Configure chip to enable crystal oscillator
+  output glitch filtering. Setting this flag will increase power consumption.
+
+Example:
+	ds1341: rtc@68 {
+		compatible = "dallas,ds1341";
+		dallas,disable-oscillator-stop-flag;
+		dallas,enable-glitch-filter;
+		reg = <0x68>;
