Detailed Description

DMA runtime status structure

busy - is current DMA transfer busy or idle dir - DMA transfer direction pending_length - data length pending to be transferred in bytes or platform dependent. free - free buffer space write_position - write position in a circular dma buffer read_position - read position in a circular dma buffer
