Yes, you have to implement both. In general, the codec chip corresponds to DAC/ADC and the controller to DMA. You can create a generic ac97-codec driver (as ALSA does) since the AC-link connection is strictly defined. The controller is the real hardware-specific thing and this cannot be generalized, of course.
