2012-07-17extcon: arizona: Stop microphone detection if we give up on itMark Brown
There should be no point in continuing to try to detect a microphone any more so stop doing so. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-07-17extcon: arizona: Update cable reporting calls and split headsetMark Brown
Use extcon_set_state_ for performance and split the headset into separate headphone and microphone reports as this is more idiomatic. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-06-26Extcon: Arizona: Add driver for Wolfson Arizona class devicesMark Brown
Most Wolfson Arizona class audio hub CODECs include a flexible ultra low power accessory detection subsystem. This driver exposes initial support for this subsystem via the Extcon framework, implementing support for ultra low power detection of headphone and headset with the ability to detect the polarity of a headset. The functionality of the devices is much richer and more flexible than the current driver, future patches will extend the features of the driver to more fully exploit this.
