Pull core irq updates from Thomas Gleixner: "Updates from the irq departement: - Update the interrupt spreading code so it handles numa node with different CPU counts properly. - A large overhaul of the ARM GiCv3 driver to support new PPI and SPI ranges. - Conversion of all alloc_fwnode() users to use physical addresses instead of virtual addresses so the virtual addresses are not leaked. The physical address is sufficient to identify the associated interrupt chip. - Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips. - Enforce interrupt threading at compile time if RT is enabled. - Small updates and improvements all over the place" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) irqchip/gic-v3-its: Fix LPI release for Multi-MSI devices irqchip/uniphier-aidet: Use devm_platform_ioremap_resource() irqdomain: Add the missing assignment of domain->fwnode for named fwnode irqchip/mmp: Coexist with GIC root IRQ controller irqchip/mmp: Mask off interrupts from other cores irqchip/mmp: Add missing chained_irq_{enter,exit}() irqchip/mmp: Do not use of_address_to_resource() to get mux regs irqchip/meson-gpio: Add support for meson sm1 SoCs dt-bindings: interrupt-controller: New binding for the meson sm1 SoCs genirq/affinity: Remove const qualifier from node_to_cpumask argument genirq/affinity: Spread vectors on node according to nr_cpu ratio genirq/affinity: Improve __irq_build_affinity_masks() irqchip: Remove dev_err() usage after platform_get_irq() irqchip: Add include guard to irq-partition-percpu.h irqchip/mmp: Do not call irq_set_default_host() on DT platforms irqchip/gic-v3-its: Remove the redundant set_bit for lpi_map irqchip/gic-v3: Add quirks for HIP06/07 invalid GICD_TYPER erratum 161010803 irqchip/gic: Skip DT quirks when evaluating IIDR-based quirks irqchip/gic-v3: Warn about inconsistent implementations of extended ranges irqchip/gic-v3: Add EPPI range support ...

Pull ARM DT updates from Arnd Bergmann: "This is another huge branch with close to 450 changessets related to devicetree files, roughly half of this for 32-bit and 64-bit respectively. There are lots of cleanups and additional hardware support for platforms we already support based on SoCs from Renesas, ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers. A total of 6 new SoCs and 37 new boards gets added this time, one more SoC will come in a follow-up branch. Most of the new boards are for 64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7. Going more into details for SoC platforms with new hardware support: - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform, usually paired with an external 5G modem. So far we only support the Qualcomm SM8150 MTP reference platform, but no actual products. - For the slightly older Qualcomm platforms, support for several interesting products is getting added: Three laptops based on Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed" aka Wileyfox Swift). - Mediatek MT7629 is a new wireless network router chip, similar to the older MT7623. It gets added together with the reference board implementation. - Allwinner V3 is a repackaged version of the existing low-end V3s chip, and is used in the tiny Lichee Pi Zero plus, also added here. There is also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the eMMC variant of the Olimex A64-Olinuxino development board. - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family, similar to the i.MX8M Mini. As usual, there is a large number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight Innovations i.MX7 RMU2 board. - In a different NXP product line, the Layerscape LS1046A "Freeway" reference board gets added. - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their set-top-box line and smart speaker with newer CPU and GPU cores compared to their predecessors. Both are now also supported by the Khadas VIM3 development board series, and the dts files for that get reorganized a bit to better deal with all variants. Another board based on SM1 that gets added is the SEI Robotics SEI610. - There are a handful of new x86 and Power9 server boards using Aspeed BMC chips that are gaining support for running Linux on the BMC through the OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably these are still new machines using SoCs based on the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based AST2600 is still ramping up. - There are three new end-user products using 32-bit Rockchips SoCs: Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings(digital signage, PoS, ...). - One more single-board computer based on the popular 64-bit RK3399 is added: the Leez RK3399 P710" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (467 commits) arm64: dts: qcom: Add Lenovo Yoga C630 ARM: dts: aspeed-g5: Fixe gpio-ranges upper limit ARM; dts: aspeed: mihawk: File should not be executable ARM: dts: aspeed: swift: Change power supplies to version 2 ARM: dts: aspeed: vesnin: Add secondary SPI flash chip ARM: dts: aspeed: vesnin: Add wdt2 with alt-boot option ARM: dts: aspeed-g4: Add all flash chips ARM: dts: exynos: Enable GPU/Mali T604 on Arndale board ARM: dts: exynos: Enable GPU/Mali T604 on Chromebook Snow ARM: dts: exynos: Add GPU/Mali T604 node to Exynos5250 ARM: dts: exynos: Fix min/max buck4 for GPU on Arndale board ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi Chromebooks ARM: dts: exynos: Remove not accurate secondary ADC compatible arm64: dts: rockchip: limit clock rate of MMC controllers for RK3328 arm64: dts: meson-sm1-sei610: add stdout-path property back arm64: dts: meson-sm1-sei610: enable DVFS arm64: dts: khadas-vim3: add support for the SM1 based VIM3L dt-bindings: arm: amlogic: add Amlogic SM1 based Khadas VIM3L bindings arm64: dts: khadas-vim3: move common nodes into meson-khadas-vim3.dtsi arm64: dts: meson: g12a: add reset to tdm formatters ...

Pull ARM SoC platform updates from Arnd Bergmann: "The main change this time around is a cleanup of some of the oldest platforms based on the XScale and ARM9 CPU cores, which are between 10 and 20 years old. The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel IOP33x/IOP13xx platforms are removed after we determined that nobody is using them any more. The TI Davinci and NXP LPC32xx platforms on the other hand are still in active use and are converted to the ARCH_MULTIPLATFORM build, meaning that we can compile a kernel that works on these along with most other ARMv5 platforms. Changes toward that goal are also merged for IOP32x, but additional work is needed to complete this. Patches for the remaining ARMv5 platforms have started but need more work and some testing. Support for the new ASpeed AST2600 gets added, this is based on the Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and ARMv6 chips in the same family. Other changes include a cleanup of the ST-Ericsson ux500 platform and the move of the TI Davinci platform to a new clocksource driver" [ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being buildable on other platforms through COMPILE_TEST, but that causes new warnings that I most definitely do not want to see during the merge window as that could hide other issues. So the COMPILE_TEST option got disabled for them again - Linus ] * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (61 commits) ARM: multi_v5_defconfig: make DaVinci part of the ARM v5 multiplatform build ARM: davinci: support multiplatform build for ARM v5 arm64: exynos: Enable exynos-chipid driver ARM: OMAP2+: Delete an unnecessary kfree() call in omap_hsmmc_pdata_init() ARM: OMAP2+: move platform-specific asm-offset.h to arch/arm/mach-omap2 ARM: davinci: dm646x: Fix a typo in the comment ARM: davinci: dm646x: switch to using the clocksource driver ARM: davinci: dm644x: switch to using the clocksource driver ARM: aspeed: Enable SMP boot ARM: aspeed: Add ASPEED AST2600 architecture ARM: aspeed: Select timer in each SoC dt-bindings: arm: cpus: Add ASPEED SMP ARM: imx: stop adjusting ar8031 phy tx delay mailmap: map old company name to new one @microchip.com MAINTAINERS: at91: remove the TC entry MAINTAINERS: at91: Collect all pinctrl/gpio drivers in same entry ARM: at91: move platform-specific asm-offset.h to arch/arm/mach-at91 MAINTAINERS: Extend patterns for Samsung SoC, Security Subsystem and clock drivers ARM: s3c64xx: squash samsung_usb_phy.h into setup-usb-phy.c ARM: debug-ll: Add support for r7s9210 ...

Pull GPIO updates from Linus Walleij: "This is the bulk of changes in the GPIO subsystem for the v5.4 kernel cycle. Core changes: - Support hierarchical GPIO irqchips. We now have three consumers that can use this: Intel IXP4xx, ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem). The support code has been long in the making and hashed out so it should be easily adaptable for all hierarchical irqchip parents. The code only gets compiled in if hierarchical irqchip is used at the topmost irq controller at least, as the hierarchical irqchip requires strict hierarchy all the way up in the system. - Determine the need for a "valid_mask" for GPIO lines on the gpio_chip and conversely for the "valid_mask" for the GPIO interrupt chip interrupt lines by looking for a .init_valid_mask() callback in the main chip or GPIO interrupt chip respectively. Allocate it with bitmap_alloc(). - Isolate the device tree/open firmware GPIO description code out in its own file properly. - Isolate the ACPI GPIO description code out in its own file properly. - Drop a whole lot of #ifdef:s in the main includes: it does not hurt to keep the include items around, and we get quicker and clearer compile failures if the appropriate kernel symbols are not selected for drivers. New/deleted drivers: - New driver for Aspeed SGPIO. - The KS8695 driver is deleted as the platform gets deleted from arch/arm in this kernel cycle. - The Cirrus Logic Madera driver now supports CS47L92 and CS47L15. - The Freescale MPC8xxx now supports LS1028A and LS1088A. Driver improvements: - We pass the GPIO irqchip intialization by directly filling in the struct instead of using set-up functions (the new way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.

Fix the example to correctly reflect the hardware in the AST2500, however it should be noted that the MMIO region is reduced to 64kiB in the AST2600 where a second SD controller block has been introduced into the address space.
