wm8958_mic_detect - Enable microphone detection via the WM8958 IRQ

: WM8958 codec : jack to report detection events on

Enable microphone detection functionality for the WM8958. By default simple detection which supports the detection of up to 6 buttons plus video and microphone functionality is supported.

The WM8958 has an advanced jack detection facility which is able to support complex accessory detection, especially when used in conjunction with external circuitry. In order to provide maximum flexiblity a callback is provided which allows a completely custom detection algorithm.

	)

wm8994_mic_detect - Enable microphone detection via the WM8994 IRQ

: WM8994 codec : jack to report detection events on : microphone bias to detect on

Enable microphone detection via IRQ on the WM8994. If GPIOs are being used to bring out signals to the processor then only platform data configuration is needed for WM8994 and processor GPIOs should be configured using snd_soc_jack_add_gpios() instead.

Configuration of detection levels is available via the micbias1_lvl and micbias2_lvl platform data members.
