Yes sure. The dependence is only on the Kconfig side: I plan to make
some drivers dependent on this configuration variable.
The goal is to submit the final driver addition without having to send
again a correction to the Kconfig after the chip/board support is merged.

This will ease the submission process at the cost of a two lines dummy
patch and will remove interdependence between subsystem trees: it worth
it, is not it?

Yes sure, I also understood like this.
I will not spread ARCH_AT91SAM9X5 ifdef in driver code...
