Merge tag 'arm-soc-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann: "The main changes this time are for the organization of the Kconfig files, introducing per-vendor top-level options on arm64 to match those on arm32, and making the platform selection on arm32 more uniform, in particular for the remaining StrongARM platforms that still have a couple of special cases compared to the more recent ones. I also did a cleanup of the old Footbridge platform, which was the last holdout for the phys_to_dma()/dma_to_phys() interface that is now completely gone from arm32, completing work started by Christoph Hellwig" * tag 'arm-soc-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (21 commits) ARM: aspeed: Kconfig: Fix indentation ARM: Drop CMDLINE_* dependency on ATAGS ARM: Drop CMDLINE_FORCE dependency on !ARCH_MULTIPLATFORM ARM: s3c: remove orphan declarations from arch/arm/mach-s3c/devs.h pxa: Drop if with an always false condition ARM: orion: fix include path ARM: shmobile: Drop selecting SOC_BUS arm64: renesas: Drop selecting SOC_BUS ARM: disallow PCI with MMU=n again ARM: footbridge: remove custom DMA address handling MAINTAINERS: Add BCM4908 maintainer to BCMBCA entry ARM: footbridge: move isa-dma support into footbridge ARM: footbridge: remove leftover from personal-server ARM: footbridge: remove addin mode arm64: Kconfig.platforms: Group NXP platforms together arm64: Kconfig.platforms: Re-organized Broadcom menu ARM: make ARCH_MULTIPLATFORM user-visible ARM: fix XIP_KERNEL dependencies ARM: Kconfig: clean up platform selection ARM: simplify machdirs/platdirs handling ...
