Merge tag 'arm-drivers-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM driver updates from Olof Johansson:

 - Reset controllers: Adding support for Microchip Sparx5 Switch.

 - Memory controllers: ARM Primecell PL35x SMC memory controller driver
   cleanups and improvements.

 - i.MX SoC drivers: Power domain support for i.MX8MM and i.MX8MN.

 - Rockchip: RK3568 power domains support + DT binding updates,
   cleanups.

 - Qualcomm SoC drivers: Amend socinfo with more SoC/PMIC details,
   including support for MSM8226, MDM9607, SM6125 and SC8180X.

 - ARM FFA driver: "Firmware Framework for ARMv8-A", defining management
   interfaces and communication (including bus model) between partitions
   both in Normal and Secure Worlds.

 - Tegra Memory controller changes, including major rework to deal with
   identity mappings at boot and integration with ARM SMMU pieces.
