The third cell "offset" is necessary so that the size field has a number
space that can include it.

Can you expand on that sentence a bit more; I don't quite understand
that aspect. Thanks.

The meaning of "size"(in the context of "reg" which is phys,size) is
"the device occupies a
contiguous sequence of addresses beginning at phys and continuing to
phys+size-1". The
implicit addition occurs on the last #size-cells cells of the phys.

Ah right of course - that makes perfect sense. Thanks.
