* 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>;
reg = <0x68>;
};
