This you can just set in the card struct, no need for explicit code at all.

It seems very odd to have namespacing on the individual property names. Why are you doing that? The properties are already defined in terms of the device binding. Though everyone else is doing it so not really a problem.
- /*
* The port numbering in the hardware manual starts at 1, while* the audmux API expects it starts at 0.*/- int_port--;
- ext_port--;
Should have error checking somewhere to make sure that the user remembered this.

I'm not sure we've really gained much from converting to a platform driver given that the device just registers something globally...
