+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

If you say yes here you get support for the
Dallas/Maxim DS1390/93/94 chips.
- This driver only supports the RTC feature, and not other chip
- features such as alarms and trickle charging.
+ This driver supports the RTC feature and trickle charging but not
+ other chip features such as alarms.
This driver can also be built as a module. If so, the module
will be called rtc-ds1390.
