Subject: [PATCH v4 0/3] ASoC: codecs: msm8916-wcd-analog: Add support to MBHC

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.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.

Tested it on DB410c with Audio Mezz board with 4 pole and 3 pole
and during playback and recording use cases.

Changes since v3(https://lkml.org/lkml/2017/8/2/609):
	- dropped ASoC: codecs: msm8916-wcd-analog: move codec reset to probe
	- fixed rampup time for micbias spotted by Mark.
	- Added tested-by from Dimien
	- Dropped dt patch from this series.
