7 title: Microchip I2S Multi-Channel Controller
10   - Codrin Ciubotariu <codrin.ciubotariu@microchip.com>
13   The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and
15   multi-channel audio codecs. It consists of a receiver, a transmitter and a
17   Client or Controller modes with receiver and/or transmitter active.
18   On later I2SMCC versions (starting with Microchip's SAMA7G5) I2S
19   multi-channel is supported by using multiple data pins, output and
