Linus Torvalds e23dd95cfd spi: Updates for v6.11

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.
 
  - 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.
