PROCESSOR-SDK-AM65X: The RGB Parallel Interface output is not supported in the latest Linux SDK

Hi,

  The RGB Parallel Interface output is not supported in the latest Linux SDK. could you supply support for this feature.

Without this feature, we can not implement the basic display feature like supply VGA monitor support with the ADV7123 chip.

Best Regards,

Michael

    Michael, 

    There is an example DTS file at:

    <sdk>board-support/linux-5.4.106+gitAUTOINC+023faefa70-g023faefa70/arch/arm64/boot/dts/ti/k3-am654-evm-hdmi.dtso

    which configures pinmux and clocks and DSS for parallel output. It was designed for an HDMI daughter card, but the daughter card was never release for external use.

    If you have a customer board that have the ADV device on it, you can rename the overlay_files to the HDMI dtbo (the binary is already built and included in the SDK release), and boot Linux to test. 

    regards
