Changes in V5: - [PATCH 1/5] rearranging code in dmaengine/dw_dmac: don't call callback routine in case dmaengine_terminate_all() is called Changes in V4: - spin_locks are not taken anymore from parent routines. Now every routine takes locks whenever required. - 1 and 0 are replaced with true and false for bool parameters to routines. - flags are not used uninitialized for spin_lock_irqsave 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.
