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.
