		struct snd_soc_jack *	jack
	)

wm8962_mic_detect - Enable microphone detection via the WM8962 IRQ

: WM8962 codec : jack to report detection events on

Enable microphone detection via IRQ on the WM8962. If GPIOs are being used to bring out signals to the processor then only platform data configuration is needed for WM8962 and processor GPIOs should be configured using snd_soc_jack_add_gpios() instead.

If no jack is supplied detection will be disabled.
