    4 Required properties :
    5  - compatible : "maxim,max17040", "maxim,max17041", "maxim,max17043",
    6                 "maxim,max17044", "maxim,max17048", "maxim,max17049",
    7                 "maxim,max17058", "maxim,max17059" or "maxim,max77836-battery"
    8  - reg: i2c slave address
    9 
   10 Optional properties :
   11 - maxim,alert-low-soc-level :   The alert threshold that sets the state of
   12                                 charge level (%) where an interrupt is
   13                                 generated. Can be configured from 1 up to 32
   14                                 (%). If skipped the power up default value of
   15                                 4 (%) will be used.
   16 - maxim,double-soc :            Certain devices return double the capacity.
   17                                 Specify this boolean property to divide the
   18                                 reported value in 2 and thus normalize it.
   19                                 SOC == State of Charge == Capacity.
   20 - maxim,rcomp :                 A value to compensate readings for various
   21                                 battery chemistries and operating temperatures.
   22                                 max17040,41 have 2 byte rcomp, default to
   23                                 0x97 0x00. All other devices have one byte
   24                                 rcomp, default to 0x97.
   25 - interrupts :                  Interrupt line see Documentation/devicetree/
   26                                 bindings/interrupt-controller/interrupts.txt
   27 - wakeup-source :               This device has wakeup capabilities. Use this
   28                                 property to use alert low SOC level interrupt
   29                                 as wake up source.
   30 
   31 Optional properties support interrupt functionality for alert low state of
   32 charge level, present in some ICs in the same family, and should be used with
   33 compatible "maxim,max77836-battery".
   34 
   35 Example:
   36 
   37         battery-fuel-gauge@36 {
   38                 compatible = "maxim,max77836-battery";
   39                 reg = <0x36>;
   40                 maxim,alert-low-soc-level = <10>;
   41                 interrupt-parent = <&gpio7>;
   42                 interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
   43                 wakeup-source;
   44         };
   45 
   46         battery-fuel-gauge@36 {
   47                 compatible = "maxim,max17048";
   48                 reg = <0x36>;
   49                 maxim,rcomp = /bits/ 8 <0x56>;
   50                 maxim,alert-low-soc-level = <10>;
   51                 maxim,double-soc;
   52         };
