-
-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>;
