git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull new ARM SoC support from Arnd Bergmann: "There are two new SoC families this time, and both appear fairly similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core Cortex-A35 based chips for the low-power industrial embedded market, and they mark the first 64-bit product in a widely used family of 32-bit Arm MCUs and SoCs. The way into the kernel is completely different here: The team at ST has a long history of working upstream with their STM32MP1 and other SoCs, and they produced a complete port to arm64 together with the initial announcement. Nuvoton also has multiple SoC product lines with current or previous upstream support, but those are maintained by third parties and are unrelated. The patch series from Nuvoton's Jacky Huang had to go through many revisisions to get to this point and is still missing a few drivers including the serial port for the moment.

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 ...

Commit 370f696e4474 ("dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties") documented dma-names property to handle Allwinner D1 dtbs_check warnings, but relies on the rx->tx ordering, which is the reverse of what a different board expects: rk3326-odroid-go2.dtb: serial@ff030000: dma-names:0: 'rx' was expected A quick and incomplete check shows the inconsistency is present in many other DTS files: $ git grep -A10 snps,dw-apb-uart | grep dma-names | sort -u arch/arm64/boot/dts/rockchip/px30.dtsi- dma-names = "tx", "rx"; arch/arm64/boot/dts/rockchip/rk3328.dtsi- dma-names = "tx", "rx"; arch/arm64/boot/dts/rockchip/rk3588s.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/rk3066a.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/rk3128.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/rk3288.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/rv1126.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/socfpga.dtsi- dma-names = "tx", "rx"; arch/arm/boot/dts/sun6i-a31.dtsi- dma-names = "rx", "tx"; arch/arm/boot/dts/sun8i-a23-a33.dtsi- dma-names = "rx", "tx"; arch/arm/boot/dts/sun8i-v3s.dtsi- dma-names = "rx", "tx"; arch/arm/boot/dts/sunxi-h3-h5.dtsi- dma-names = "rx", "tx"; arch/riscv/boot/dts/allwinner/sunxi-d1s-t113.dtsi- dma-names = "rx", "tx"; The initial proposed solution was to allow a flexible dma-names order in the binding, due to potential ABI breakage concerns after fixing the DTS files.
