I wouldn't mind a bit more information on what "stability" issues
entails! I'm a sucker for details in a commit message.
Yep, giving us a bit more than "doesnt work" may help us help you!

I keep seeing Konrad requesting that we use the #define instead of a raw
number 0, i.e. something like QCOM_ICC_TAG_ALWAYS (although if I'm
reading that correctly QCOM_ICC_TAG_ALWAYS doesn't evaluate to 0, so
make sure you pick the appropriate one).
No it doesn't, but if you look at the code, tag being non-existent
assigns QCOM_ICC_TAG_ALWAYS which is a workaround for DTBs from back
when interconnect tags were not a thing
+ interconnect-names = "pcie-mem", "cpu-pcie";
This is nitpicky, but unless someone told you to do the whitespace
between some of these properties I'd get more consistent. i.e. reg and
reg-names has no newline between them, but clocks and clock-names does,
and then interconnects/interconnect-names does not.
