Merge tag 'spi-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull SPI updates from Mark Brown:
 "A quiet release for SPI, some fixes and small updates for individual
  drivers with one bigger change from Linus Walleij which coverts the
  bitbanging SPI driver to use the GPIO descriptor API from Linus
  Walleij.

  Since GPIO descriptors were used by platform data this means there's a
  few changes in arch/ making relevant updates for a few platforms and
  one misc driver that are affected"
