1QCOM WCD9335 Codec
2
3Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC, supports
4Qualcomm Technologies, Inc. (QTI) multimedia solutions, including
5the MSM8996, MSM8976, and MSM8956 chipsets. It has in-built
6Soundwire controller, interrupt mux. It supports both I2S/I2C and
7SLIMbus audio interfaces.
