Merge tag 'spi-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "There's been quite a lot of generic activity here, but more
  administrative than featuers. We also have a bunch of new drivers,
  including one that's part of a MFD so we pulled in the core parts of
  that:

   - Lots of work from both Yang Yingliang and Andy Shevchenko on moving
     to host/device/controller based terminology for devices.

   - QuadSPI SPI support for Allwinner sun6i.

   - New device support Cirrus Logic CS43L43, Longsoon, Qualcomm GENI
     QuPv3 and StarFive JH7110 QSPI"
