Microchip's new SAMA7G5 includes an updated I2S-MCC compatible with the
previous version found on SAM9X60. The new controller includes 8 (4 * 2)
input and output data pins for up to 8 channels for I2S and Left-Justified
formats.

 	  The I2SMCC complies with the Inter-IC Sound (I2S) bus specification
