  15 * PL330 can assign any channel to communicate with
  16 * any of the peripherals attched to the DMAC.
  17 * For the sake of consistency across client drivers,
  18 * We keep the channel names unchanged and only add
  19 * missing peripherals are added.
  20 * Order is not important since DMA PL330 API driver
  21 * use these just as IDs.
