If there is really the need to put more information (which I don't
see in the case of the RTCs) to .config, it might be an idea to
extend the current structure for this use instead of duplicating
and maintaining a second repository.

And regarding the DS1337 (or the PCF8563 and similar RTCs):
It's address (0x68) is immutable fixed by the manufacturer
of that device. So, why do we include it in the DT, when we
already told the kernel what driver we want to use?

Even if I have an eeprom which can have varying addresses,
I can simply tell the driver/the kernel .config what address
it should use... If I want to be able to alter that address
for whatever reason by OF, I still don't want to touch a
separate file in the kernel tree.
