  29           By default, the DMA arbitration scheme is based on Round-robin
  30           (rx:tx priority is 1:1).

  39           to use the TMU channel 2 and the SH-RTC device.

  62           (RING) and linked-list(CHAINED) mode. In RING mode each descriptor
  63           points to two data buffer pointers whereas in CHAINED mode they
  64           points to only one data buffer pointer.
