2011-02-13ASoC: WM8903: Fix mic detection register definitionsStephen Warren
* There is no hysteresis enable field in the current datasheet. * Mic detection threshold field is only 2 bits wide. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2010-03-16ASoC: Implement interrupt driven microphone detection for WM8903Mark Brown
Support use of the WM8903 IRQ for reporting of microphone presence and short detection. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-03-16ASoC: Add WM8903 interrupt supportMark Brown
Currently used to detect completion of the write sequencer. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-03-16ASoC: Initial WM8903 microphone bias and short detectionMark Brown
Provide support for WM8903 microphone presence and short detection using the GPIOs to route out a logic signal suitable for handling using snd_soc_jack_add_gpios() on the processor GPIOs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-03-16ASoC: Add GPIO configuration support for WM8903Mark Brown
Allow users to pass in a default configuration for the GPIOs of the WM8903 as platform data. This allows configuration of the pin muxing of the device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
