Integrate new device tree generated from cubeMX as the base for the yocto build.

[Itsmefaska]

I'm facing a problem when trying to build an image for my mp257f-eval board using a custom device tree generated from cubemx. I've followed the instructions from the following wiki : https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package#Creating_a_new_open_embedded_layer_for_your_demo But the build fails when trying to compile optee, because the device tree does contains a reference for a pll device not declared earlier. i did some lookups inside the working directory, and i found it declared in the recipes-security/optee folder under meta-st-stm32mp meta layer (https://github.com/STMicroelectronics/meta-st-stm32mp/blob/scarthgap/recipes-security/optee/optee-os/0001-4.0.0-stm32mp-r2.patch). i guess the patch is not applied to the device tree, only the standard device trees for common boards get patched. i don't know if someone has faced a similar problem and can help? I'll attach the log and configs files using for the build. thanks in advance.

The log of the error is the following :
