Currently it's 5.19.0-rc7 (torvalds tree at 4ba1329c) with a few extra

To test patches you should apply them on maintainer's tree or
linux-next. Applying on other trees of course might be useful for
testing some backports, but it is independent process and different
issue.

I think you may be right; I just applied this patchset to -next
(20220722) and i do not see the error message there. On my 5.19-rc7
tree, i am also testing a patchset that enables qcom devices to access
efivars, so possibly we are ending up in secure world there?
Actually mapping of IO space should not touch secure world, so this was
a long shot assuming you test it on the next.
The memory region specified in device tree overlaps with the llcc system
cache controller node. Steev probably had the QCOM_LLCC config enabled
when he tested it out on his branch.

Good catch! You are correct, my -next config did not have QCOM_LLCC
set, and I am using QCOM_LLCC=m on the 5.19.0 release candidate.
