   4 Required properties :
   5  - compatible : "maxim,max17040" or "maxim,max77836-battery"
   6  - reg: i2c slave address
   7
   8 Optional properties :
   9 - maxim,alert-low-soc-level :   The alert threshold that sets the state of
  10                                 charge level (%) where an interrupt is
  11                                 generated. Can be configured from 1 up to 32
  12                                 (%). If skipped the power up default value of
  13                                 4 (%) will be used.
  14 - interrupts :                  Interrupt line see Documentation/devicetree/
  15                                 bindings/interrupt-controller/interrupts.txt
  16 - wakeup-source :               This device has wakeup capabilities. Use this
  17                                 property to use alert low SOC level interrupt
  18                                 as wake up source.
  19
  20 Optional properties support interrupt functionality for alert low state of
  21 charge level, present in some ICs in the same family, and should be used with
  22 compatible "maxim,max77836-battery".

  24 Example:
  25
  26         battery-fuel-gauge@36 {
  27                 compatible = "maxim,max77836-battery";
  28                 reg = <0x36>;
  29                 maxim,alert-low-soc-level = <10>;
  30                 interrupt-parent = <&gpio7>;
  31                 interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
  32                 wakeup-source;
  33         };
