Merge tag 'arm-soc-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann: "This is mostly 32-bit code for SoC platforms, and looks smaller than any such branch I remember from previous kernels, as most of this is now handled in other subsystems for modern platforms: - Minor bugfixes and Kconfig updates for Tegra, Broadcom, i.MX, Renesas, and Samsung - Updates to the MAINTAINERS listing for Actions, OMAP, and Samsung - Samsung SoC driver updates to make them loadable modules" * tag 'arm-soc-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: MAINTAINERS: arm: samsung: include S3C headers in platform entry MAINTAINERS: Add linux-actions ML for Actions Semi Arch ARM: s3c: irq-s3c24xx: staticize local functions ARM: s3c: irq-s3c24xx: include headers for missing declarations ARM: s3c: fix fiq for clang IAS ARM: imx: Remove unused IMX_GPIO_NR() macro soc: renesas: rcar-sysc: Mark device node OF_POPULATED after init ARM: OMAP2+: fix spellint typo MAINTAINERS: Update address for OMAP GPMC driver soc: renesas: rcar-sysc: Use readl_poll_timeout_atomic() ARM: bcm: Select BRCMSTB_L2_IRQ for bcm2835 ARM: brcmstb: Add debug UART entry for 72116 ARM: tegra: Don't enable unused PLLs on resume from suspend soc: samsung: pm_domains: Convert to regular platform driver soc: samsung: exynos-chipid: correct helpers __init annotation ARM: mach-imx: imx6ul: Print SOC revision on boot ARM: imx: mach-imx6ul: remove 14x14 EVK specific PHY fixup soc: samsung: exynos-chipid: convert to driver and merge exynos-asv soc: samsung: exynos-asv: handle reading revision register error soc: samsung: exynos-asv: don't defer early on not-supported SoCs
