* 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>;
|
||||
};
