+modelgauge_battery
+~~~~~~~~~~~~~~~~~~
+
+Required properties:
+ - compatible : should contain one of the following:
+ - "maxim,max17040" for MAX17040
+ - "maxim,max17041" for MAX17041
+ - "maxim,max17043" for MAX17043
+ - "maxim,max17044" for MAX17044
+ - "maxim,max17048" for MAX17048
+ - "maxim,max17049" for MAX17049
+ - "maxim,max17058" for MAX17058
+ - "maxim,max17059" for MAX17059
+
+Optional properties:
+ - maxim,empty_alert_threshold : Capacity threshold where an interrupt is
+ generated on the ALRT pin;
+
+ - soc_change_alert : /* alert for 1% soc change */
+ - hibernate_threshold : Hibernate threshold (crate), where IC
+ enters hibernate mode
+ - active_threshold : Active threshold (mV), where IC exits
+ hibernate mode
+ - undervoltage : Voltage (mV), when IC alerts while battery
+ voltage less then undervoltage
+ - overvoltage : Voltage (mV), when IC alerts while battery
+ voltage greater then overvoltage
+ - maxim,resetvoltage : Voltage threshold (mV) below which the IC
+ resets itself. Used to detect battery removal
+ and reinsertion;
+ - maxim,empty_adjustment : Capacity charge empty design value;
+ - maxim,full_adjustment : Capacity charge full design value;
+ - maxim,rcomp0 : ModelGauge RCOMP parameter, used for
+ temperature compensation;
+ - maxim,temp_co_up : ModelGauge TempCoUp parameter, used for
+ temperature compensation;
+ - maxim,temp_co_down : ModelGauge TempCoDown parameter, used for
+ temperature compensation;
+ - maxim,ocvtest : ModelGauge OCVTest parameter, used for
+ verification of Custom Model calibration data
+ loaded into IC RAM;
+ - maxim,soc_check_a : ModelGauge SOCCheckA parameter, used for
+ verification of Custom Model calibration data
+ loaded into IC RAM;
+ - maxim,soc_check_b : ModelGauge SOCCheckB parameter, used for
+ verification of Custom Model calibration data
+ loaded into IC RAM;
+ - maxim,bits : ModelGauge Bits parameter, used as
+ scaling parameter in Custom Model algorithm;
+ - maxim,model_data : ModelGauge ModelData data,
+ Custom Model calibration data.
