What if 4 PCM-instances are not enough?

Hi,

we are developing a ALSA-device driver for the SEK'D/Marian ARC88,
which has 4 analog stereo IO's and a digital IO.
So there's is that little problem, that there only could be two combinations:
4 analog IO/0 digital
3 analog IO/1 digital,
which should IMHO be taken under attack in the future.

I am reading LDD3 at the moment and wondered how the best use of the 2.6 dev_t,
which doesn't limit the minors to 255, the starting point for my problem.

Is there a solution insight, which doesn't break compatibility with older apps?

Greets,
Henne
