This bit is OK but...

...for simple card since the whole idea is to support any CODEC with the
same driver we should probably just make sure that all the individual
drivers can be enabled in Kconfig, that way we don't have to have
specific Kconfig entries for boards and loose some of the benefit of the
generic card.  I sent a patch earlier exposing the OF supporting CODEC
drivers, one for at least some of the Freescale CPU drivers was sent to
the list recently too but there were some review comments.
