• 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@0 {

    compatible = "dallas,ds1390";
    trickle-resistor-ohms = <250>;
    reg = <0>;
  

  };
