Merge tag 'spi-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "Only one framework update this time around, a change from Lars-Peter
  to move full to pm_ops and remove the legacy bus PM ops.  Otherwise
  it's all driver updates:

   - make the spidev driver complain loudly if registered as spidev with
     DT rather than with a compatible string, hopefully helping people
     avoid making that mistake.

   - error handling and robustness fixes for the Designware and Intel
     MID drivers from Andy Shevchenko.

   - substantial performance improvements for the Raspberry Pi driver
     from Martin Sperl.

   - several new features for spidev_test from Adrian Remonda and Ian
     Abbott"
