Detailed Description

struct dma_chan - devices supply DMA channels, clients use them : ptr to the dma device who supplies this channel, always !NULL : last cookie value returned to client : last completed cookie for this channel : channel ID for sysfs : class device for sysfs : used to add this to the device chan list : per-cpu pointer to a struct dma_chan_percpu -count: how many clients are using this channel : number of appearances in the mem-to-mem allocation table : private data for certain client-channel associations
