Alexandre Bounine 50835e977b rapidio/tsi721_dma: rework scatter-gather list handling ... Rework Tsi721 RapidIO DMA engine support to allow handling data scatter/gather lists longer than number of hardware buffer descriptors in the DMA channel's descriptor list. The current implementation of Tsi721 DMA transfers requires that number of entries in a scatter/gather list provided by a caller of dmaengine_prep_rio_sg() should not exceed number of allocated hardware buffer descriptors. This patch removes the limitation by processing long scatter/gather lists by sections that can be transferred using hardware descriptor ring of configured size. It also introduces a module parameter "dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware buffer descriptor rings.
