 "One new core feature here, a small collection of new drivers and a
  bunch of small improvements in existing drivers:

   - A new CS_WORD flag for transfers where the chip select is toggled
     at every word, with both a generic implementation and the ability
     for controllers to do this automatically (including a DaVinci one).

   - New drivers for Mediatek MT2712, Qualcomm GENI and QSPI, Spreadtrum
     SPI and ST STM32 QSPI plus new IDs for several existing ones"

 "A small update with a couple of new APIs that are useful for some
  small sets of devices:

   - Split up the single_rw flagging to map read and write separately as

 "First batch of dma-mapping changes for 4.20.

  There will be a second PR as some big changes were only applied just
  before the end of the merge window, and I want to give them a few more
  days in linux-next.

  Summary:

   - mostly more consolidation of the direct mapping code, including
     converting over hexagon, and merging the coherent and non-coherent
     code into a single dma_map_ops instance (me)

   - cleanups for the dma_configure/dma_unconfigure callchains (me)

   - better handling of dma_masks in odd setups (me, Alexander Duyck)

   - better debugging of passing vmalloc address to the DMA API (Stephen
     Boyd)
