Merge tag 'spi-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "The overwhelming bulk of this pull request is a change from Uwe
  Kleine-König which changes the return type of the remove() function to
  void as part of some wider work he's doing to do this for all bus
  types, causing updates to most SPI device drivers. The branch with
  that on has been cross merged with a couple of other trees which added
  new SPI drivers this cycle, I'm not expecting any build issues
  resulting from the change.

  Otherwise it's been a relatively quiet release with some new device
  support, a few minor features and the welcome completion of the
  conversion of the subsystem to use GPIO descriptors rather than
  numbers:

   - Change return type of remove() to void.

   - Completion of the conversion of SPI controller drivers to use GPIO
     descriptors rather than numbers.

   - Quite a few DT schema conversions.

   - Support for multiple SPI devices on a bus in ACPI systems.

   - Big overhaul of the PXA2xx SPI driver.

   - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
     MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
     Sunplus SP7021"

[ And this is obviously where that spi change that snuck into the
  regulator tree _should_ have been :^]
