31 *
32 * @reset: GPIO controlling /RESET (NULL = none)
33 * @ldo1: Substruct of pdata for the LDO1 regulator
34 * @micvdd: Substruct of pdata for the MICVDD regulator
35 * @irq_flags: Mode for primary IRQ (defaults to active low)
36 * @gpio_base: Base GPIO number
37 * @gpio_configs: Array of GPIO configurations (See Documentation/pinctrl.txt)
38 * @n_gpio_configs: Number of entries in gpio_configs
39 * @gpsw: General purpose switch mode setting. Depends on the external
40 * hardware connected to the switch. (See the SW1_MODE field
41 * in the datasheet for the available values for your codec)
