Merge tag 'arm-soc-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
"These are updates for SoC specific code, mostly in the 32-bit
architecture:

- A rework for handling MMIO accesses in Renesas SoCs in a more
portable way

- Updates to SoC version detection in NXP i.MX SoCs.

- Smaller bug fixes for OMAP, Samsung, Marvell, Amlogic"
