Merge tag 'dmaengine-4.13-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul:

 - removal of AVR32 support in dw driver as AVR32 is gone

 - new driver for Broadcom stream buffer accelerator (SBA) RAID driver

 - add support for Faraday Technology FTDMAC020 in amba-pl08x driver

 - IOMMU support in pl330 driver

 - updates to bunch of drivers
