* Dallas DS1390 SPI Serial Real-Time Clock
Required properties:
- compatible: Should contain "dallas,ds1390".
- reg: SPI address for chip
Optional properties:
- trickle-resistor-ohms : Selected resistor for trickle charger
Values usable for ds1390 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:
ds1390: rtc@68 {
compatible = "dallas,ds1390";
trickle-resistor-ohms = <250>;
reg = <0>;
};
