Merge tag 'spi-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "A respun version of the merges for the pull request previously sent
  with a few additional fixes.  The last two merges were fixed up by
  hand since the branches have moved on and currently have the prior
  merge in them.

  Quite a busy release for the SPI subsystem, mostly in cleanups big and
  small scattered through the stack rather than anything else:

   - New driver for the Broadcom BC63xx HSSPI controller
   - Fix duplicate device registration for ACPI
   - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
     changes upon which the transiton depends)
   - Some small optimisations to reduce the amount of time we hold locks
     in the datapath, eliminate some redundant checks and the size of a
     spi_transfer
   - Lots of fixes, cleanups and general enhancements to drivers,
     especially the rspi and Atmel drivers"
