Merge tag 'soc-drivers-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "The most notable updates this time are for Qualcomm Snapdragon
  platforms. The Inline-Crypto-Engine gets a new DT binding and driver,
  and a number of drivers now support additional Snapdragon variants, in
  particular the rsc, scm, geni, bwm, glink and socinfo, while the llcc
  (edac) and rpm drivers get notable functionality updates.

  Updates on other platforms include:

   - Various updates to the Mediatek mutex and mmsys drivers, including
     support for the Helio X10 SoC

   - Support for unidirectional mailbox channels in Arm SCMI firmware

   - Support for per cpu asynchronous notification in OP-TEE firmware

   - Minor updates for memory controller drivers.

   - Minor updates for Renesas, TI, Amlogic, Apple, Broadcom, Tegra,
     Allwinner, Versatile Express, Canaan, Microchip, Mediatek and i.MX
     SoC drivers, mainly updating the use of MODULE_LICENSE() macros and
     obsolete DT driver interfaces"
