+ * @rx_dws: DMA slave interface to use for sound capture.
+ * @tx_dws: DMA slave interface to use for sound playback.
+ * @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.
+ * @flags: 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.
