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