BTW, DE 3.0 includes a register in DE TOP called "DE IP configure register",
which gives the number of IP blocks per class, per mixer. If we retrieve the
configuration from this register, then we shouldn't need to differentiate
between mixer-0 and mixer-1 with compatible strings.
What do you think?
