+* Dallas DS1339 I2C Serial Real-Time Clock
+
+Required properties:
+- compatible: Should contain "dallas,ds1339".
+- reg: I2C address for chip
+
+Optional properties:
+- trickle-resistor-ohms : Selected resistor for trickle charger
+ Values usable for ds1339 are 250, 2000, 4000
+ Should be given if trickle charger should be enabled
+- trickle-diode-enable : Use internal trickle charger diode
+ Should be given if internal trickle charger diode should be enabled
+Example:
+ ds1339: rtc@68 {
+ compatible = "dallas,ds1339";
+ trickle-resistor-ohms = <250>;
+ reg = <0x68>;
+ };
Documentation: dt-bindings: trickle charger dt binding document for ds1339 Some DS13XX devices have "trickle chargers". Introduce a device tree binding for the resistor and diode configuration for enabling trickle charger.
