SAMA7G5 includes an updated version of I2S-MCC, found previously on
SAM9X60. 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.
