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.
