RK3399的PMIC:RK808在LDO6下输出2.5V

如题:PMIC的电压配置如下:        (与电路图匹配)
                vcc1-supply = <&vcc5v0_sys>;
        vcc2-supply = <&vcc5v0_sys>;
        vcc3-supply = <&vcc5v0_sys>;
        vcc4-supply = <&vcc5v0_sys>;
        vcc6-supply = <&vcc5v0_sys>;
        vcc7-supply = <&vcc5v0_sys>;
        vcc8-supply = <&vcc3v3_sys>;
        vcc9-supply = <&vcc3v3_sys>;
        vcc10-supply = <&vcc5v0_sys>;
        vcc11-supply = <&vcc5v0_sys>;
        vcc12-supply = <&vcc3v3_sys>;
        vddio-supply = <&vcc1v8_pmu>;
io-domain:
    bt656-supply = <&vcc_3v0>;        /* bt656_gpio2ab_ms */
    audio-supply = <&vcc_3v0>;    /* audio_gpio3d4a_ms */
    sdmmc-supply = <&vcc_sd>;        /* sdmmc_gpio4b_ms */
    gpio1830-supply = <&vcc_3v0>;        /* gpio1833_gpio4cd_ms */

        pmu1830-supply = <&vcc_3v0>;

结果pmu的ldo6出来的电压是 2.5V,不是1.5V

改错:vcc9-supply = <&vcc5v0_sys>;
