 * @reset_pin: 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.

 * 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.
