Merge tag 'spi-v3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi 

Pull spi fixes from Mark Brown:
 "A scattering of driver specific fixes here.

  The fixes from Axel cover bitrot in apparently unmaintained drivers,
  the at79 bug is fixing a glitch on /CS during initialisation of some
  devices which could break some slaves and the remainder are fixes for
  recently introduced bugs from the past release cycle or so"

* tag 'spi-v3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: atmel: add missing spi_master_{resume,suspend} calls to PM callbacks
  spi: coldfire-qspi: Fix getting correct address for *mcfqspi
  spi: fsl-dspi: Fix getting correct address for master
  spi: spi-ath79: fix initial GPIO CS line setup
  spi: spi-imx: spi_imx_remove: do not disable disabled clocks
  spi-topcliff-pch: Fix probing when DMA mode is used
  spi/topcliff-pch: Fix DMA channel
