Stm32mp157c DRM (No connector&encoder)

I’m dealing with Odyssey Stm32mp157c board. I booted the board with st official yocto package. The board is working but i have a problem with drm. CRTCs are exist but there is no connector or encoder in the output of modetest. Also i cant run any Qt gui application. It gives no connector error.

My question is where should i look? what could be the reason for that. I couldn’t figure out and appreciate any help. I attached the dmesg and modetest outputs. Thx.

For those facing with the same problem, I figured out you need to add all ltdc endpoints to ltdc node. After doing that i was able to run drm.
