2、qcom,panel-supply-entry in the panel .dtsi files as shown below in kernel/arch/arm64/boot/dts/qcom/sdm660-mdss-panels.dtsi
3、通过在相应的mdss_dsi节点中指定面板电源调节器，将电源映射到电路板文件中的稳压器，如下所示：
/kernel/arch/arm64/boot/dts/ qcom/sdm660-mdss.dtsi 4、具体lab、ibb电源设置见文件：pm660l.dtsi中配置LDO和NCP相关配置，
vddio的配置见sdm660-regulator.dtsi文件中的pm660l-L11的配置； 5、相关的寄存器查看在adb下查看：
