1* Dallas DS1390		SPI Serial Real-Time Clock
2
3Required properties:
4- compatible: Should contain "dallas,ds1390".
5- reg: SPI address for chip
6
7Optional properties:
8- trickle-resistor-ohms : Selected resistor for trickle charger
9	Values usable for ds1390 are 250, 2000, 4000
10	Should be given if trickle charger should be enabled
11- trickle-diode-disable : Do not use internal trickle charger diode
12	Should be given if internal trickle charger diode should be disabled
13Example:
14	ds1390: rtc@0 {
15		compatible = "dallas,ds1390";
16		trickle-resistor-ohms = <250>;
17		reg = <0>;
18	};
