如何添加PMI芯片下的CHG_LED功能

以MSM8953平臺爲例，需要添加以下兩條屬性（默認爲紅燈）

&pmi8950_charger {

        qcom,battery-data = <&qrd_batterydata>;

        qcom,float-voltage-mv = <4350>;

        qcom,override-usb-current;

        qcom,chg-led-sw-controls;

        qcom,chg-led-support;

        /*qcom,external-typec;

        qcom,typec-psy-name = "typec";*/

        qcom,thermal-mitigation = <2250 2250 2250 2250 2200 700 0>;

        status = "okay";

}
