Yeah.  So please put that in the binding.

Something like that, yes.  You wrote milliseconds before; which is it?

And, a better property name, please.

In the binding for nand devices.  If there isn't any yet, it might be
best to include that with the binding for your nand controller (i.e.,
describe the whole sub node there).
