-max17040_battery
-~~~~~~~~~~~~~~~~
-
-Required properties :
- - compatible : "maxim,max17040", "maxim,max17041", "maxim,max17043",
- "maxim,max17044", "maxim,max17048", "maxim,max17049",
- "maxim,max17058", "maxim,max17059" 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.
-- maxim,double-soc : Certain devices return double the capacity.
- Specify this boolean property to divide the
- reported value in 2 and thus normalize it.
- SOC == State of Charge == Capacity.
-- maxim,rcomp : A value to compensate readings for various
- battery chemistries and operating temperatures.
- max17040,41 have 2 byte rcomp, default to
- 0x97 0x00. All other devices have one byte
- rcomp, default to 0x97.
-- 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;
- };
-
- battery-fuel-gauge@36 {
- compatible = "maxim,max17048";
- reg = <0x36>;
- maxim,rcomp = /bits/ 8 <0x56>;
- maxim,alert-low-soc-level = <10>;
- maxim,double-soc;
- };
