Merge tag 'spi-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This release sees some exciting changes from David Lechner which
  implements some optimisations that have been talked about for a long
  time which allows client drivers to pre-prepare SPI messages for
  repeated or low latency use. This lets us move work out of latency
  sensitive paths and avoid repeating work for frequently performed
  operations. As well as being useful in itself this will also be used
  in future to allow controllers to directly trigger SPI operations (eg,
  from interrupts).

  Otherwise this release has mostly been focused on cleanups, plus a
  couple of new devices:

   - Support for pre-optimising messages

   - A big set of updates from Uwe Kleine-König moving drivers to use
     APIs with more modern terminology for controllers

   - Major overhaul of the s3c64xx driver

   - Support for Google GS101 and Samsung Exynos850"
