description:
  The RZ/G3E (R9A09G047) sound controller is based on R-Car Sound IP
  with extended DMA channel support (up to 5 DMACs per direction),
  additional clock domains (47 clocks including per-SSI ADG clocks),
  and additional reset lines (14 including SCU, ADG and Audio DMAC
  peri-peri resets). SSI operates exclusively in BUSIF mode with
  2-4 BUSIF channels per SSI.
