Did I do something wrong or we just need to enhance regmap_debugfs.c?

Do you assign the name field in pru_regmap_config and
pru_debug_regmap_config?

Yeah, you'll at least need to override the name since the default is to
use the name of the device and that'll result in two duplicates.

Also combining IO regions often has a serious issue that the
separate IO regions may not be in the same device (or same
interconnect target module).

This means that flushing a posted write with a read-back for
an IO region will only flush it for a single device and not
the other(s). And this leads into hard to find bugs :)
