* 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>;

       };
