Subject: [PATCH V5 0/5] dmaengine/dw_dmac updates

This patchset fixes few issues and extends its support.

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.

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
