QCOM WCD9335 Codec



Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC, supports

Qualcomm Technologies, Inc. (QTI) multimedia solutions, including

the MSM8996, MSM8976, and MSM8956 chipsets. It has in-built

Soundwire controller, interrupt mux. It supports both I2S/I2C and

SLIMbus audio interfaces.
