BQ27220: The issue about bq27000 chip (Devices tree)

Part Number: BQ27220

From Documentation\devicetree\bindings\power\supply\bq27xxx.txt

Example:

       bat: battery { compatible = "simple-battery";

              voltage-min-design-microvolt = <3200000>;

              energy-full-design-microwatt-hours = <5290000>;

              charge-full-design-microamp-hours = <1430000>; };

       bq27510g3: fuel-gauge@55 { compatible = "ti,bq27510g3";

              reg = <0x55>;

              monitored-battery = <&bat>; };

Does only those three parameters  voltage-min-design-microvolt / energy-full-design-microwatt-hours / charge-full-design-microamp-hours we need to config?

From the Internet:

It sees we need to config other more parameter,could you help to tell me which parameter Which parameters we must configure?

Thanks
