32 * @irq_flags: Mode for primary IRQ (defaults to active low)

37 * @gpsw: General purpose switch mode setting. Depends on the external
38 * hardware connected to the switch. (See the SW1_MODE field
39 * in the datasheet for the available values for your codec)
40 * @codec: Substruct of pdata for the ASoC codec driver
