Merge tag 'arm-soc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "The code changes are mostly for 32-bit platforms and include:

   - Lots of updates for the Nvidia Tegra platform, including cpuidle,
     pmc, and dt-binding changes

   - Microchip at91 power management updates for the recently added
     sam9x60 SoC

   - Treewide setup_irq deprecation by afzal mohammed

   - STMicroelectronics stm32 gains earlycon support

   - Renesas platforms with Cortex-A9 can now use the global timer

   - Some TI OMAP2+ platforms gain cpuidle support

   - Various cleanups for the i.MX6 and Orion platforms, as well as
     Kconfig files across all platforms"
