It is quite common for mfd drivers to pass regmap information to
child drivers. Child drivers typically call dev_get_regmap() with
the parent device as parameter. Granted, that is typically used
for spi or i2c devices, but I don't see why it would not work
here as well.

Then there s syscon, but I don't know if that works with overlapping
memory regions.
