-* 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-disable : Do not use internal trickle charger diode
-       Should be given if internal trickle charger diode should be disabled
-Example:
-       ds1339: rtc@68 {
-               compatible = "dallas,ds1339";
-               trickle-resistor-ohms = <250>;
