    ASoC: rt5514: add rt5514 SPI driver · 6eebf35b
    Oder Chiou authored
    The device has multiple control interfaces, I2C and SPI. The I2C interface
    mainly controls the register settings of codec. The SPI interface is in
    order to provide the high speed transmission of data. For example, high
    bandwidth memory read/write of DSP. The patch adds the rt5514 SPI driver
    for loading the firmware of DSP and retrieving the voice data from DSP
    after the system is waked up by specific voice.
