This series brings improvements to the STM32 DMA driver, with support of
power management and descriptor reuse. Probe function gets a cleanup and
properties like copy_align and max_segment_size are set.
A "sleeping function called from invalid context" bug is also fixed. And
to avoid a race with vchan_complete, driver now adopts
vchan_terminate_vdesc().

Amelie Delaunay (4):
  dmaengine: stm32-dma: use dma_set_max_seg_size to set the sg limit
  dmaengine: stm32-dma: add copy_align constraint
  dmaengine: stm32-dma: fix sleeping function called from invalid
    context
  dmaengine: stm32-dma: use vchan_terminate_vdesc() in .terminate_all

Etienne Carriere (2):
  dmaengine: stm32-dma: use reset controller only at probe time
  dmaengine: stm32-dma: driver defers probe for reset

Pierre-Yves MORDRET (2):
  dmaengine: stm32-dma: add suspend/resume power management support
  dmaengine: stm32-dma: enable descriptor_reuse

Applied, thanks
