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" * tag 'arm-soc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (75 commits) ARM: qcom: Add support for IPQ40xx ARM: mmp: replace setup_irq() by request_irq() ARM: cns3xxx: replace setup_irq() by request_irq() ARM: spear: replace setup_irq() by request_irq() ARM: ep93xx: Replace setup_irq() by request_irq() ARM: iop32x: replace setup_irq() by request_irq() arm: mach-dove: Mark dove_io_desc as __maybe_unused ARM: orion: replace setup_irq() by request_irq() ARM: debug: stm32: add UART early console support for STM32MP1 ARM: debug: stm32: add UART early console support for STM32H7 ARM: debug: stm32: add UART early console configuration for STM32F7 ARM: debug: stm32: add UART early console configuration for STM32F4 cpuidle: tegra: Disable CC6 state if LP2 unavailable cpuidle: tegra: Squash Tegra114 driver into the common driver cpuidle: tegra: Squash Tegra30 driver into the common driver cpuidle: Refactor and move out NVIDIA Tegra20 driver into drivers/cpuidle ARM: tegra: cpuidle: Remove unnecessary memory barrier ARM: tegra: cpuidle: Make abort_flag atomic ARM: tegra: cpuidle: Handle case where secondary CPU hangs on entering LP2 ARM: tegra: Make outer_disable() open-coded ...
