I prefer to add dt data about max14577-muic on following:
If extcon consumer driver need to use muic device, dts should provide following dt data.
muic: max14577-muic {
compatible = "maxim, max14577-muic";
};
> + };

For example,
If fuel-gauge want to use extcon subsystem, dt data of fuel-gauge add 'extcon' property as following:
fuel-gague@ {
compatible = "...";
extcon = <&muic>;
}
Thanks,
