max17040_battery
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
Required properties :
|
|
- compatible : "maxim,max17040" or "maxim,max77836-battery"
|
|
- reg: i2c slave address
|
|
|
|
Optional properties :
|
|
- maxim,alert-low-soc-level : The alert threshold that sets the state of
|
|
charge level (%) where an interrupt is
|
|
generated. Can be configured from 1 up to 32
|
|
(%). If skipped the power up default value of
|
|
4 (%) will be used.
|
|
- interrupts : Interrupt line see Documentation/devicetree/
|
|
bindings/interrupt-controller/interrupts.txt
|
|
- wakeup-source : This device has wakeup capabilities. Use this
|
|
property to use alert low SOC level interrupt
|
|
as wake up source.
|
|
|
|
Optional properties support interrupt functionality for alert low state of
|
|
charge level, present in some ICs in the same family, and should be used with
|
|
compatible "maxim,max77836-battery".
|
|
|
|
Example:
|
|
|
|
battery-fuel-gauge@36 {
|
|
compatible = "maxim,max77836-battery";
|
|
reg = <0x36>;
|
|
maxim,alert-low-soc-level = <10>;
|
|
interrupt-parent = <&gpio7>;
|
|
interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
|
|
wakeup-source;
|
|
};
