This patchset fixes few issues and extends its support.
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.
Linus Walleij (1): dmaengine/dw_dmac: implement pause and resume in dwc_control
Viresh Kumar (4): dmaengine/dw_dmac: don't call callback routine in case dmaengine_terminate_all() is called dmaengine/dw_dmac: set residue as total len in dwc_tx_status if status is !DMA_SUCCESS dmaengine/dw_dmac: Divide one sg to many desc, if sg len is greater than DWC_MAX_COUNT dmaengine/dw_dmac: Replace spin_lock* with irqsave variants and enable submission from callback
