[PATCH v2 2/8] ASoC: codecs: wcd937x: add wcd937x codec driver
From: Mohammad Rafi Shaik
Date: Tue Apr 16 2024 - 02:37:32 EST
From: Prasad Kumpatla <quic_pkumpatl@xxxxxxxxxxx>
This patch adds basic SoundWire codec driver to support for
WCD937X TX and RX devices.
WCD937x has Multi Button Headset Control hardware to support Headset
insertion, type detection, 8 headset buttons detection, Over Current
detection and Impedence measurements.
This patch adds support for this using wcd-mbhc apis.
