Also perhaps memory size (and offset if
needed) to be mapped for peripherals can go with reg
property of child.

Which detail are you referring to here? The only "size" property that is
effective is the one of the generic GPMC block, and there it's in the
"reg"-property.

I was referring to that of child, now in gpmc_nand_init(),
gpmc_cs_request() is being done, later on if we want to
make it generic and remove gpmc_nand_init(), additional
information that would be required from DT at least is the
memory size to be reserved in gpmc address space for
the connected peripheral (assuming gpmc_cs_request()
would be done by gpmc driver generically later)

What I had in mind was example for external bus in [1],
but I had not looked deep into this aspect yet.
