2024-08-08	ASoC: dt-bindings: qcom,wcd939x: Correct reset GPIO polarity in example	Krzysztof Kozlowski
	The reset GPIO of WCD9390/WCD9395 is active low and that's how it is routed on typical boards, so correct the example DTS to use expected polarity, instead of IRQ flag (which is a logical mistake on its own).

2024-01-22	ASoC: dt-bindings: document WCD939x Audio Codec	Neil Armstrong
	Document the Qualcomm WCD9390/WCD9395 Audio Codec and the Soundwire devices than can be found on Qualcomm SM8650 based platforms. The Qualcomm WCD9390/WCD9395 Audio Codec communicates with the host SoC over 2 Soundwire links to provide: - 4 ADC inputs for up to 5 Analog Microphones - 4 DMIC inputs for up to 8 Digital Microphones - 4 Microphone BIAS - Stereo Headphone output - Mono EAR output - MBHC engine for Headset Detection The WCD9390/WCD9395 IC has separate I2C subsystem for USB-C DP Altmode/Audio Accessory mode Mux which is not documented here but requires port/endpoint graph and properties to handle Altmode/Audio Accessory switch and orientation.
