If you run that under strace -e file
on what file access does it start to hang?
After a bit more investigation, the "offending" files are
/sys/kernel/debug/regmap/dummy-system-controller@f06f4000/registers
/sys/kernel/debug/regmap/dummy-system-controller@f2440000/registers
When trying to read these, eventually the system will lock up. It looks like these register ranges cover offsets that cause errors when trying to read them.
Interestingly, the other two regmaps
/sys/kernel/debug/regmap/dummy-system-controller@f06f8000/registers
/sys/kernel/debug/regmap/dummy-system-controller@f2400000/registers
are fine.
So lacking an easy way to set up holes in regmap via dts, lacking documentation about these register ranges, and the fact that you can only access this as root, my suggestion for now is "avoid accessing those files".

i was looking for something using grep command on the whole filesystem
grep -rn / -e "remapping interface"
and unit crashed (i tried 2 times it crashed 2 times)
