   2
   3 Required properties:
   4 - compatible: Should contain "dallas,ds1390".
   5 - reg: SPI address for chip
   6
   7 Optional 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
  13 Example:
  14         ds1390: rtc@68 {
  15                 compatible = "dallas,ds1390";
  16                 trickle-resistor-ohms = <250>;
  17                 reg = <0>;
  18         };
