Changes in V3: - lflags is removed from dw_dma_chan and local flag variables are created. - An extra argument is added to routines calling dwc_descriptor_complete() directly or indirectly - spin_lock() in tasklet is also changed to irqsave variants. Changes in V2: - lflags added in dw_dma_chan instead of dw_dma - Patch from Linus Walleij added for pause and resume functionality.
