Detailed Description

struct atmel_ac97c_pdata - board specific AC97C configuration : DMA slave interface to use for sound capture. : DMA slave interface to use for sound playback. : GPIO pin wired to the reset input on the external AC97 codec, optional to use, set to -ENODEV if not in use. AC97 layer will try to do a software reset of the external codec anyway. : Flags for which directions should be enabled.

If the user do not want to use a DMA channel for playback or capture, i.e. only one feature is required on the board. The slave for playback or capture can be set to NULL. The AC97C driver will take use of this when setting up the sound streams.
