+chip connected accordingly.

+Optional properties:
+ - maxim,low-battery-dac-enable: Enable low battery monitoring.
+ Low battery monitoring will be disabled if missing
+ this property.
+ - maxim,low-battery-mode: Shutdown or reset the chip.
+ The value of this property is "shutdown" which means
+ a global shutdown will be triggered. Any other values
+ or missing this property causes a chip reset.
