From: Srinivas Kandagatla <srinivas.kandaga...@linaro.org> This patchset adds support to MBHC(Multibutton headset control) block in PM8916 analog block. MBHC support comes from 2 blocks first mechanical headset detection and second headset type, 5 button detection.
This patchset adds support to: 1> Support to NC and NO type of headset Jacks. 2> Mechanical insertion and detection of headset jack. 3> Detect a 3 pole Headphone and a 4 pole Headset. 4> Detect 5 buttons. Damien sent a similar patchset to add support to mechanical detection, but that patch has issues and will not work on most usecases (for example after a playback/capture session, multicodec case). So I only picked up the BIT mask patch from that series. Tested it on DB410c with Audio Mezz board with 4 pole and 3 pole and during playback and recording use cases. Changes since v2(https://lkml.org/lkml/2017/8/2/609): - cleaned up code spotted by Damien - dropped fix snd_soc_codec_set_jack return error as it alredy applied Srinivas Kandagatla (5): ASoC: codecs: msm8916-wcd-analog: move codec reset to probe ASoC: codecs: msm8916-wcd-analog: get micbias voltage from dt ASoC: codecs: msm8916-wcd-analog: add MBHC support ASoC: qcom: apq8016-sbc: Add support to Headset JACK arm64: dts: apq8016-sbc: add mbhc buttons support .../bindings/sound/qcom,msm8916-wcd-analog.txt | 18 +- arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi | 2 + sound/soc/codecs/msm8916-wcd-analog.c | 407 +++++++++++++++++++-- sound/soc/qcom/apq8016_sbc.c | 34 ++ 4 files changed, 437 insertions(+), 24 deletions(-) -- 2.9.3
