spi: Updates for v4.1 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.
