Subject: [PATCH v2 0/4] ASoC: codecs: wcd934x: add Headset and button detection support
Date: Mon, 24 May 2021 12:06:56 +0100 [thread overview]
Message-ID: <20210524110700.27077-1-srinivas.kandagatla@linaro.org> (raw)
This patchset adds support to MBHC(Multi Button Headset Control) block found in
Qualcomm WCD codecs. MBHC support headset type detection, both Mechanical and
electrical insert/removal detection along with 8 buttons detection,
Over current interrupts on HPHL/R, Impedance Measurements on HPHL/R.
Eventhough MBHC block supports things like OverCurrent detection, Currently its
reported as a kernel debug message. Should this be reported as an uevent to
userspace? like the way USB reports?
Any suggestions?
First patch adds a common mbhc driver and the second one wcd934x specific driver
changes along with sdm845 soundcard related changes.
Common wcd-mbhc-v2 driver should be reusable across multiple codecs like
WCD9335, WCD934x, WCD937x and WCD938x.
Most of the work is derived from downstream Qualcomm kernels.
Credits to various Qualcomm authors from Patrick Lai's team who have
contributed to this code.
This patchset
thanks,
srini
