git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC updates from Olof Johansson: "A few SoC (code) changes have queued up this cycle, mostly for minor changes and some refactoring and cleanup of legacy platforms. This branch also contains a few of the fixes that weren't sent in by the end of the release (all fairly minor). - Adding an additional maintainer for the TEE subsystem (Sumit Garg) - Quite a significant modernization of the IXP4xx platforms by Linus Walleij, revisiting with a new PCI host driver/binding, removing legacy mach/* include dependencies and moving platform detection/config to drivers/soc. Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...

2021-06-21dt-bindings: Drop redundant minItems/maxItemsRob Herring4-6/+0
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

BCM4908 is a SoC family with PCIe controller sharing design with the one for STB. BCM4908 has different power management and memory controller so few tweaks are required. PERST# signal on BCM4908 is handled by an external MISC block so it needs specifying a reset phandle.

2020-12-11dt-bindings: pci: rcar-pci-ep: Document missing interrupts propertyGeert Uytterhoeven1-0/+9
The R-Car PCIe controller does not use interrupts when configured for endpoint mode, hence the bindings do not document the interrupts property. However, all DTS files provide interrupts properties, and thus fail to validate. Fix this by documenting the interrupts property.

2020-10-07dt-bindings: Explicitly allow additional properties in common schemasRob Herring4-0/+8
In order to add meta-schema checks for additional/unevaluatedProperties being present, all schema need to make this explicit. As common/shared schema are included by other schemas, they should always allow for additionalProperties.
