Why?

And why your DTS is in the middle of driver changes? Driver cannot
depend on DTS - you are now breaking all existing boards and users.


Best regards,

I was following a similar patch which has DT and driver changes in the
same patchset:
https://lore.kernel.org/all/20230314080443.64635-1-manivannan.sadhasivam@linaro.org/

The AND region was added in the IP block in SM8450, but was not added to the DT or
driver. That is why I included both in the same patchset - if you think the DT
changes should be separate I can correct it in the next version.

Thanks a lot for taking the time to review Krzysztof.

Just move the DT changes to be the last patches in the patchset.
