    ASoC: mchp-i2s-mcc: add driver for I2SC Multi-Channel Controller · b87d37d0
    Codrin Ciubotariu authored
    The Inter-IC Sound Controller (I2SMCC) provides a 5-wire, bidirectional,
    synchronous, digital audio link to external audio devices: I2SMCC_DIN,
    I2SMCC_DOUT, I2SMCC_WS, I2SMCC_CK, and I2SMCC_MCK pins.
    The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and
    supports a Time Division Multiplexed (TDM) interface with external
    multi-channel audio codecs.
    The I2SMCC consists of a receiver, a transmitter and a common clock
    generator that can be enabled separately to provide Master, Slave or
    Controller modes with receiver and/or transmitter active.
    DMA Controller channels, separate for the receiver and for the transmitter,
    allow a continuous high bit rate data transfer without processor
    intervention to the following:
     - Audio CODECs in Master, Slave, or Controller mode
     - Stereo DAC or ADC through a dedicated I2S serial interface
     - Multi-channel or multiple stereo DACs or ADCs, using the TDM format
    
    This IP is embedded in Microchip's new sam9x60 SoC.
