Detailed Description

struct middma_device - internal representation of a DMA device : PCI device : MMIO register space pointer of DMA : for allocating DMA descriptors : embedded struct dma_device : dma tasklet for processing interrupts : per channel data : DMA device PCI ID : Interrupt mask to be used : MMIO register for periphral mask : Base ch index (read from driver data) : max number of chs supported (from drv_data) : Block size of DMA transfer supported (from drv_data) : MMIO register addr for periphral interrupt (from drv_data) : dma PM device state
