STM32MP135 ST PMIC Driver panic

We designed a STM32MP135 based SOM, without using the ST I2C PMIC,  I was able to disable the PMIC driver in TF-A by removing the i2c 4 node in TF-A's dts file, while I could not get the same result for optee-os,  even I removed the i2c-4 node in optee-os' dts file, I still got message saying panic, following is the full log:

You will most likely need to take STMicro's OPTEE reference software and make some changes.    It may be possible to remove the power management features using a build configuration flag, but it may require some code changes as well.   I ran into a similar issue when removing secure storage support from OPTEE.     Looking at this file for the version you are using might help with some configurations to search for.

Hello, Mr. efancier, I have the same problem as you, the same panic. Have you modified it now? Ask for your advice

Dear Mr. Macdog, following your prompt, I found the conf.mk file and modified it to add my own device tree. My board uses STPMIC1D, and I still have the same problem as this post.

I hope the great God in the forum can help me, point out my mistakes or need to be modified, thank you!!

Thank you, Macdog !    seems not only the conf.mk file, but also the device tree need to be updated

Hi lebeer, I am still working on it, will let you know if there's any progress.
