Is there a AC97 Driver CONFIG_ that makes sense to wrap that with? Just wondering about the mutual exclusion (and how to provide flexibility to the user). - k
The ULI supports both the HD and AC97 interfaces, but the 8641 only supports the AC97 interface. Thus we can straight disable the HD and convert/configure the shared pins to be AC97. Thus, there is no real CONFIG_ need at all. It's only AC97. And then ultimately, the presence of sound support is controlled by the ALSA config options as per normal. Thanks, jdl
