Pull spi updates from Mark Brown:
 "This has been a very active release for the DesignWare driver in
  particular - after a long period of inactivity we have had a lot of
  people actively working on it for unrelated reasons this cycle with
  some of that work still not landed.

  Otherwise it's been fairly quiet for the subsystem.

  Highlights include:

   - Lots of performance improvements and fixes for the DesignWare
     driver from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement
     Leger, Dinh Nguyen and Jarkko Nikula.

   - Support for octal mode transfers in spidev.

   - Slave mode support for the Rockchip drivers.

   - Support for AMD controllers, Broadcom mspi and Raspberry Pi 4, and
     Intel Elkhart Lake"
