Linus Torvalds 0051db8218 spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
 with SPI NOR flashes, there's been some specific support for a while for
 controller features designed to make them perform better but it's not
 worked out as well as hoped so the interface has been redesigned in a
 way that will hopefully do better - it's already been adopted by a
 number of additional controllers so things are looking good.  Otherwise
 most of the work has been driver specific:
 
  - Support for better integration with NOR flashes from Boris Brezillon
    and Yogesh Narayan Gaur plus usage of it in several drivers.
  - A big cleanup of the Rockchip driver from Emil Renner Berthing.
  - Lots of performance improvements for bcm2835 from Lukas Wunner.
  - Slave mode support for pxa2xx from Lubomir Rintel.
  - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
    and Renesas r8a77470.
