This controller includes 8 data pins, 4 for playback and 4 for capture. For I2S and LEFT_J formats, these pins can be used to send/receive up to 8 audio channels. For DSP_A, with TDM, any pins pair (DIN/DOUT) from these 4 can be selected to send/receive data. This version also includes 2 FIFOs (send and receive). This patch set starts by moving the driver's bindings to yaml and continues with adding a new compatible for the SAMA7G5 variant, followed by the changes needed for I2S/LEFT_J support, TDM pin pair selection and FIFO support, exclusively for SAMA7G5.
