-~~~~~~~~~~~~~~~~
-
-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".

-
-       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>;
