Merge tag 'dmaengine-4.18-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:

 - updates to sprd, bam_dma, stm drivers

 - remove VLAs in dmatest

 - move TI drivers to their own subdir

 - switch to SPDX tags for ima/mxs dma drivers

 - simplify getting .drvdata on bunch of drivers by Wolfram Sang
