git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull devicetree updates from Rob Herring: "DT core: - Add support for generating DT nodes for PCI devices. This is the groundwork for applying overlays to PCI devices containing non-discoverable downstream devices. - DT unittest additions to check reverted changesets, to test for refcount issues, and to test unresolved symbols. Also, various clean-ups of the unittest along the way. - Refactor node and property manipulation functions to better share code with old API and changeset API - Refactor changeset print functions to a common implementation - Move some platform_device specific functions into of_platform.c Bindings: - Treewide fixing of typos - Treewide clean-up of SPDX tags to use 'OR' consistently - Last chunk of dropping unnecessary quotes.

2023-06-29Merge tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/socLinus Torvalds
Pull ARM SoC devicetree updates from Arnd Bergmann: "The biggest change this time is for the 32-bit devicetree files, which are all moved to a new location, using separate subdirectories for each SoC vendor, following the same scheme that is used on arm64, mips and riscv. This has been discussed for many years, but so far we never did this as there was a plan to move the files out of the kernel entirely, which has never happened. The impact of this will be that all external patches no longer apply, and anything depending on the location of the dtb files in the build directory will have to change. The installed files after 'make dtbs_install' keep the current location. There are six added SoCs here that are largely variants of previously added chips. Two other chips are added in a separate branch along with their device drivers. - The Samsung Exynos 4212 makes its return after the Samsung Galaxy Express phone is addded at last. The SoC support was originally added in 2012 but removed again in 2017 as it was unused at the time. - Amlogic C3 is a Cortex-A35 based smart IP camera chip - Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of the still common MSM8916 (Snapdragon 410) phone chip that has been supported for a long time. - Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end laptop chips, used in the Lenovo Flex 5G, which is added along with the reference board. - Qualcomm SDX75 is the latest generation modem chip that is used as a peripherial in phones but can also run a standalone Linux. Unlike the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55. - Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the Xuantie C910 core, a step up from all previously added rv64 chips. All of the above come with reference board implementations, those included there are 39 new board files, but only five more 32-bit this time, probably a new low: - Marantec Maveo board based on dhcor imx6ull module - Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip - Epson Moverio BT-200 AR glasses based on TI OMAP4 - PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM - ICnova ADB4006 board based on Allwinner A20 On the 64-bit side, there are also fewer addded machines than we had in the recent releases: - Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device. - NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234 - Qualcomm gains support for 6 reference boards on various members of their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top of the various reference platforms for their new chips. - Rockchips support for several newer boards: Indiedroid Nova (rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn Fastrhino R66S/R68S (rk3568) - TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex Verdin family with AM62 COM, carrier and dev boards Other changes to existing boards contain the usual minor improvements along with - continued updates to clean up dts files based on dtc warnings and binding checks, in particular cache properties and node names - support for devicetree overlays on at91, bcm283x - significant additions to existing SoC support on mediatek, qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST STM32MP1 As usual, a lot more detail is available in the individual merge commits" * tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (926 commits) ARM: mvebu: fix unit address on armada-390-db flash ARM: dts: Move .dts files to vendor sub-directories kbuild: Support flat DTBs install ARM: dts: Add .dts files missing from the build ARM: dts: allwinner: Use quoted #include ARM: dts: lan966x: kontron-d10: add PHY interrupts ARM: dts: lan966x: kontron-d10: fix SPI CS ARM: dts: lan966x: kontron-d10: fix board reset ARM: dts: at91: Enable device-tree overlay support for AT91 boards arm: dts: Enable device-tree overlay support for AT91 boards arm64: dts: exynos: Remove clock from Exynos850 pmu_system_controller ARM: dts: at91: use generic name for shutdown controller ARM: dts: BCM5301X: Add cells sizes to PCIe nodes dt-bindings: firmware: brcm,kona-smc: convert to YAML riscv: dts: sort makefile entries by directory riscv: defconfig: enable T-HEAD SoC MAINTAINERS: add entry for T-HEAD RISC-V SoC riscv: dts: thead: add sipeed Lichee Pi 4A board device tree riscv: dts: add initial T-HEAD TH1520 SoC device tree riscv: Add the T-HEAD SoC family Kconfig option ...

schemas Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

Make "clocks" and "power-domains" required everywhere. Make "resets" required on R-Car Gen2 and newer (i.e. all but SH-Mobile).

Enable yamllint to check the preferred commenting style of requiring a space after a comment character '#'. Fix the cases in the tree which have a warning with this enabled. Most cases just need a space after the '#'. A couple of cases with comments which were not intended to be comments are revealed. Those were in ti,sa2ul.yaml, ti,cal.yaml, and brcm,bcmgenet.yaml.

The QSPI controller needs three reset items to work properly on JH7110 SoC, so there is need to change the maxItems's value to 3 and add minItems whose value is equal to 2. Other platforms do not have this constraint.
