Merge tag 'spi-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "A fairly standard release for SPI with the exception of a change to
  the API for specifying chip selects done in preparation for supporting
  devices with more than one chip select, this required some mechanical
  changes throughout the tree which have been cooking in -next happily
  for a while.

  There's also a new API to allow us to support TPM chips on half duplex
  controllers.

  Summary:

   - Refactoring in preparation for supporting multiple chip selects for
     a single device, needed by some flash devices, which required a
     change in the SPI device API visible throughout the tree

   - Support for hardware assisted interaction with SPI TPMs on half
     duplex controllers, implemented on nVidia Tedra210 QuadSPI

   - Optimisation for large transfers on fsl-cpm devices

   - Cleanups around device property use which fix some sisues with
     fwnode

   - Use of both void remove() and devm_platform_.*ioremap_resource()

   - Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
     Intel MetorLake-S and StarFive J7110 QuadSPI"
