There are + * more than twice as many slots as event channels. + * + * Each PaRAM set describes a sequence of transfers, either for one large + * buffer or for several discontiguous smaller buffers. An EDMA transfer + * is driven only from a channel, which performs the transfers specified + * in its PaRAM slot until there are no more transfers. When that last + * transfer completes, the "link" field may be used to reload the channel's + * PaRAM slot with a new transfer descriptor. + * + * The EDMA Channel Controller (CC) maps requests from channels into physical + * Transfer Controller (TC) requests when the channel triggers (by hardware + * or software events, or by chaining). The two physical DMA channels provided + * by the TCs are thus shared by many logical channels. + * + * DaVinci hardware also has a "QDMA" mechanism which is not currently + * supported through this interface.
