Missing display-dpoc.dtbo in Yocto BSP (25.1) for DP over Type-C Enablement

Hi MediaTek Community,

I am currently working with the MediaTek Genio 520 board with image generated using Yocto (release 25.1) and referring to the official documentation for enabling DisplayPort over Type-C (DP Alt Mode) on the G720 EVK platform:

MediaTek Display Documentation (G720 EVK)

As per the documentation, it is mentioned that enabling DP display requires loading the following device tree overlay:

display-dpoc.dtbo

Issue Observed:

I built the rity-demo-image using BSP version 25.1, but I am not finding the display-dpoc.dtbo file.

Questions:

  1. Is display-dpoc.dtbo available only for specific boards or configurations (e.g., limited to certain EVKs)?

  2. Has this overlay been removed or renamed in BSP release 25.1?

  3. Is there any additional configuration or layer that needs to be enabled to generate this DTBO?

  4. If the overlay is no longer provided, what is the recommended approach to enable DP over Type-C in this release?

Environment Details:

  • BSP Version: 25.1

  • Image: rity-demo-image

  • Build System: Yocto

  • Target Platform: Genio 520

Thank you for your support.
