    ASoC: rt5514: add rt5514 codec driver · 4a6180ea
    Oder Chiou authored
    This is the initial codec driver for rt5514. The codec includes a low power
    DSP for voice wake up. The register address is incremental by 4 in the DSP
    memory map. In order to recover the codec settings in the codec mode and
    manipulate the DSP mode for voice wake up, we use the multi-level register
    map. One is for ALSA API in codec mode that can be recovered by cache
    before recording. Another is for DSP related settings that can be accessed
    with 32bit address of the DSP in the application of voice wake up.
