Hi , TI engineer .
sdk :ti-processor-sdk-linux-am62xx-evm-08.06.00.42
ddr :512M .
I have a problem on the tidss VP2 port . Hardware we use VP2 (DSI) to outpu 24bits RGB standtard signal for RGB control chips . the RGB contol chips transforms the RGB signal to VGA port .
I configure the dts of kenel like this .

//power-supply = <&vdd_rgb>;
