Okay.

Still, I'd like to see some handling for a mismatch - the case in which the
driver says "my device can produce X" but X isn't available with that PIC/bus
combination. Or maybe provide a way (if there isn't one already) for the
driver to query the available trigger types. Some devices I've come across
have configurable interrupt generators.
