      新手请教!

      请问一下,A133 linux5.4 android11,

      	regulator0: regulators@0 {
      		reg_dcdc1: dcdc1 {
      			regulator-name = "axp2202-dcdc1";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <1540000>;
      			regulator-ramp-delay = <250>;
      			regulator-enable-ramp-delay = <1000>;
      			regulator-boot-on;
      			regulator-always-on;
      		};
      		reg_dcdc2: dcdc2 {
      			regulator-name = "axp2202-dcdc2";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <3400000>;
      			regulator-ramp-delay = <250>;
      			regulator-enable-ramp-delay = <1000>;
      			regulator-boot-on;
      			regulator-always-on;
      		};
      
      		reg_cldo1: cldo1 {
      			regulator-name = "axp2202-cldo1";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <3500000>;
      			regulator-enable-ramp-delay = <1000>;
      			regulator-boot-on;
      		};
      		reg_cldo2: cldo2 {
      			regulator-name = "axp2202-cldo2";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <3500000>;
      			regulator-enable-ramp-delay = <1000>;
      		};
      		reg_cldo3: cldo3 {
      			regulator-name = "axp2202-cldo3";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <3500000>;
      			regulator-ramp-delay = <2500>;
      			regulator-enable-ramp-delay = <1000>;
      			regulator-boot-on;
      		};
      		reg_cldo4: cldo4 {
      			regulator-name = "axp2202-cldo4";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <3500000>;
      			regulator-enable-ramp-delay = <1000>;
      		};
      		reg_cpusldo: cpusldo {
      			/* cpus */
      			regulator-name = "axp2202-cpusldo";
      			regulator-min-microvolt = <500000>;
      			regulator-max-microvolt = <1400000>;
      			regulator-boot-on;
      			regulator-always-on;
      		};
      		reg_drivevbus: drivevbus {
      			regulator-name = "axp2202-drivevbus";
      			regulator-enable-ramp-delay = <1000>;
      		};
      
      	};
      

      cldo4-supply = <&reg_cldo4>

      我用做vcc-lcd,我想输出3.3V,但是只能输出1.8V,请问如何控制其输出3.3V?

        我自己改好了,多谢

        &power_sply {
        aldo1_vol = <1101800>;
        aldo2_vol = <1101800>;
        aldo4_vol = <1001800>;
        bldo1_vol = <1800>;
        bldo2_vol = <1001800>;
        bldo4_vol = <1101800>;
        cldo1_vol = <1001800>;
        cldo3_vol = <1003300>;
        cldo4_vol = <1103300>;
        cpusldo_vol = <1000900>;
        dcdc1_mode = <1>;
        dcdc2_mode = <1>;
        bc12_mode = <0>;
        };
