This series brings improvements to the MDMA driver, with support of power
management and descriptor reuse. Probe function gets a cleanup and to avoid
a race with vchan_complete, driver now adopts vchan_terminate_vdesc().

Amelie Delaunay (2):
  dmaengine: stm32-mdma: driver defers probe for clock and reset
  dmaengine: stm32-mdma: use vchan_terminate_vdesc() in .terminate_all

Etienne Carriere (2):
  dmaengine: stm32-mdma: use reset controller only at probe time
  dmaengine: stm32-mdma: disable clock in case of error during probe

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