Detailed Description

struct shdma_ops - simple DMA driver operations desc_completed: return true, if this is the descriptor, that just has completed (atomic) halt_channel: stop DMA channel operation (atomic) channel_busy: return true, if the channel is busy (atomic) slave_addr: return slave DMA address desc_setup: set up the hardware specific descriptor portion (atomic) set_slave: bind channel to a slave setup_xfer: configure channel hardware for operation (atomic) start_xfer: start the DMA transfer (atomic) embedded_desc: return Nth struct shdma_desc pointer from the descriptor array chan_irq: process channel IRQ, return true if a transfer has completed (atomic)
