* TI BQ32000                I2C Serial Real-Time Clock

Required properties:
- compatible: Should contain "ti,bq32000".
- reg: I2C address for chip

Optional properties:
- trickle-resistor-ohms : Selected resistor for trickle charger
       Values usable are 1120 and 20180
       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:
       bq32000: rtc@68 {
               compatible = "ti,bq32000";
               trickle-resistor-ohms = <1120>;
               reg = <0x68>;
       };
