&soc?{
	dsi_panel_pwr_supply:?dsi_panel_pwr_supply?{
		#address-cells?=?<1>;
		#size-cells?=?<0>;

		qcom,panel-supply-entry@0 {
			reg?= <0>;
			qcom,supply-name?= "vdd";
			qcom,supply-min-voltage?= <2850000>;//供电一
			qcom,supply-max-voltage?= <2850000>;
			qcom,supply-enable-load?= <100000>;
			qcom,supply-disable-load?= <100>;
		};

		qcom,panel-supply-entry@1 {
			reg?= <1>;
			qcom,supply-name?= "vddio";
			qcom,supply-min-voltage?= <1800000>;//供电二
			qcom,supply-max-voltage?= <1800000>;
			qcom,supply-enable-load?= <100000>;
			qcom,supply-disable-load?= <100>;
		};
	};
};
