Merge tag 'spi-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "There's some quite exciting core work in this release, we've got the
  beginnings of support for hardware initiated transfers which is itself
  independently useful for optimising fast paths in existing drivers.

  We also have a rework of the DMA mapping which allows finer grained
  decisions about DMA mapping messages and also helps remove some bodges
  that we'd had.

  Otherwise it's a fairly quiet release, a few new drivers and features
  for existing drivers, together with various cleanups and DT binding
  conversions.

  One regmap SPI fix made it's way in here too which I should probably
  have sent as a regmap fix instead.

  Summary:

   - Support for pre-optimising messages, reducing the overhead for
     messages that are repeatedly used (eg, reading the interrupt status
     from a device). This will also be used for hardware initiated
     transfers in future.

   - A reworking of how DMA mapping is done, introducing a new helper
     and allowing the DMA mapping decision to be done per transfer
     instead of per message.

   - Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A"
