i want to port OCOTP driver for MXS, which hasn't MMIO. From my understanding

That's cool.

hexdump would readout the complete register range defined in provider DT node.

How can i achieve that hexdump only reads the data area within the register
range?

If the question is just about hexdump, then hexdump itself can read file 
from given offset and size.

But I believe the real question is "How can we dump each nvmem cell 
independently"

In one of my replies I mentioned that am planning to add sysfs entries 
under /sys/class/nvmem/<provider>/cells/

ex:
for qfprom tsens calibration it would look like:

$ hexdump /sys/class/nvmem/qfprom0/cells/tsens_calibration

0000000 e000 0c00 0c00 0000 0c00
...

Is that what you guys are looking for?
