Pull SoC devicetree updates from Arnd Bergmann: "There are a handful of new SoCs this time, all of these are more or less related to chips in a wider family: - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first widely available RVA23 implementation. Note that this is entirely unrelated with the similarly named Texas Instruments K3 chip family that follwed the TI Keystone2 SoC. - The Realtek Kent family of SoCs contains three chip models rtd1501s, rtd1861b and rtd1920s, and is related to their earlier Set-top-box and NAS products such as rtd1619, but is built on newer Arm Cortex-A78 cores. - The Qualcomm Milos family includes the Snapdragon 7s Gen 3 (SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm Cortex-A720 generation. This one is used in the Fairphone Gen 6 - Qualcomm Kaanapali is a new SoC based around eight high performance Oryon CPU cores - NXP i.MX8QP and i.MX952 are both feature reduced versions of chips we already support, i.e. the i.MX8QM and i.MX952, with fewer CPU cores and I/O interfaces. As part of a cleanup, a number of SoC specific devicetree files got removed because they did not have a single board using the .dtsi files and they were never compile tested as a result: Samsung s3c6400, ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/ r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715. All of these could be restored easily if a new board gets merged. Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only machine, as all remaining users are assumed to be using ACPI based firmware. A relatively small number of 43 boards get added this time, and almost all of them for arm64. Aside from the reference boards for the newly added SoCs, this includes: - Three server boards use 32-bit ASpeed BMCs - One more reference board for 32-bit Microchip LAN9668 - 64-bit Arm single-board computers based on Amlogic s905y4, CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020, NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588 - Two mobile phones using Snapdragon 845 - A gaming device and a NAS box, both based on Rockchips rk356x On top of the newly added boards and SoCs, there is a lot of background activity going into cleanups, in particular towards getting a warning-free dtc build, and the usual work on adding support for more hardware on the previously added machines" * tag 'soc-dt-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (757 commits) dt-bindings: intel: Add Agilex eMMC support arm64: dts: socfpga: agilex: add emmc support arm64: dts: intel: agilex5: Add simple-bus node on top of dma controller node ARM: dts: socfpga: fix dtbs_check warning for fpga-region ARM: dts: socfpga: add #address-cells and #size-cells for sram node dt-bindings: altera: document syscon as fallback for sys-mgr arm64: dts: altera: Use lowercase hex dt-bindings: arm: altera: combine Intel's SoCFPGA into altera.yaml arm64: dts: socfpga: agilex5: Add IOMMUS property for ethernet nodes arm64: dts: socfpga: agilex5: add support for modular board dt-bindings: intel: Add Agilex5 SoCFPGA modular board arm64: dts: socfpga: agilex5: Add dma-coherent property arm64: dts: realtek: Add Kent SoC and EVB device trees dt-bindings: arm: realtek: Add Kent Soc family compatibles ARM: dts: samsung: Drop s3c6400.dtsi ARM: dts: nuvoton: Minor whitespace cleanup MAINTAINERS: Add Falcon DB arm64: dts: a7k: add COM Express boards ARM: dts: microchip: Drop usb_a9g20-dab-mmx.dtsi arm64: dts: rockchip: Fix rk3588 PCIe range mappings ...

Accesses to external memory are routed through the data backbone (DBB) on Tegra264. A separate clock feeds this path and needs to be enabled whenever an IP block makes an access to external memory. The external memory controller driver is the best place to control this clock since it knows how many devices are actively accessing memory. Document the presence of this clock on Tegra264 only.

2025-12-18dt-bindings: memory: introduce DDR4Clément Le Goffic-0/+34
Introduce JEDEC compliant DDR bindings, that use new memory-props binding. The DDR4 compatible can be made of explicit vendor names and part numbers or be of the form "ddrX-YYYY,AAAA...-ZZ" when associated with an SPD, where (according to JEDEC SPD4.1.2.L-6): - YYYY is the manufacturer ID - AAAA... is the part number - ZZ is the revision ID The former form is useful when the SDRAM vendor and part number are known, for example, when memory is soldered on the board. The latter form is useful when SDRAM nodes are created at runtime by boot firmware that doesn't have access to static part number information.

2025-12-18dt-bindings: memory: factorise LPDDR props into SDRAM propsClément Le Goffic-78/+98
LPDDR and DDR bindings are SDRAM types and are likely to share the same properties (at least for density, io-width and reg). To avoid bindings duplication, factorise the properties. The compatible description has been updated because the MR (Mode registers) used to get manufacturer ID and revision ID are not present in case of DDR. Those information should be in a SPD (Serial Presence Detect) EEPROM in case of DIMM module or are known in case of soldered memory chips as they are in the datasheet of the memory chips.

Add bindings for the Memory Controller (MC) and External Memory Controller (EMC) found on the Tegra264 SoC. Tegra264 SoC has a different number of interrupt lines for MC sub-units: UCF_SOC, hub, hub common, syncpoint and MC channel. The total number of interrupt lines is eight. Update maxItems for MC interrupts accordingly. This also adds a header containing the memory client ID definitions that are used by the interconnects property in DT and the tegra_mc_client table in the MC driver. These IDs are defined by the hardware, so the numbering doesn't start at 0 and contains holes. Also added are the stream IDs for various hardware blocks found on Tegra264. These are allocated as blocks of 256 IDs and each block can be subdivided for additional fine-grained isolation if needed.

Add bindings for STM32 Octo Memory Manager (OMM) controller. OMM manages: - the muxing between 2 OSPI busses and 2 output ports. There are 4 possible muxing configurations: - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2 output is on port 2 - OSPI1 and OSPI2 are multiplexed over the same output port 1 - swapped mode (no multiplexing), OSPI1 output is on port 2, OSPI2 output is on port 1 - OSPI1 and OSPI2 are multiplexed over the same output port 2 - the split of the memory area shared between the 2 OSPI instances. - chip select selection override. - the time between 2 transactions in multiplexed mode.

2024-10-01dt-bindings: Fix array property constraintsRob Herring (Arm)-3/+2
Schemas for array properties should only have 1 level of array constraints (e.g. items, maxItems, minItems). Sometimes the old encoding of all properties into a matrix leaked into the schema, and didn't matter for validation. Now the inner constraints are just silently ignored as json-schema array keywords are ignored on scalar values. Generally, keep the inner constraints and drop the outer "items". With gicv3 "mbi-alias" property, it is more appropriately a uint32 or uint64 as it is an address and size depends on "#address-cells".

That means that the NAND controller and the PSRAM controller (if the signal is used) can not be used at the same time. On MP25 SoC, the 2 signals can be used outside the SoC, so there is no more restrictions. MP1 SoC also embeds revision 1.1 of the FMC2 IP when MP25 SoC embeds revision 2.0 of the FMC2 IP.

In particular, this contains portions of the treewide conversion to use __counted_by annotations and the device_get_match_data helper" * tag 'soc-drivers-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (156 commits) soc: qcom: pmic_glink_altmode: Print return value on error firmware: qcom: scm: remove unneeded 'extern' specifiers firmware: qcom: scm: add a missing forward declaration for struct device firmware: qcom: move Qualcomm code into its own directory soc: samsung: exynos-chipid: Convert to platform remove callback returning void soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size() soc: qcom: pmic_glink: fix connector type to be DisplayPort soc: ti: k3-socinfo: Avoid overriding return value soc: ti: k3-socinfo: Fix typo in bitfield documentation soc: ti: knav_qmss_queue: Use device_get_match_data() firmware: ti_sci: Use device_get_match_data() firmware: qcom: qseecom: add missing include guards soc/pxa: ssp: Convert to platform remove callback returning void soc/mediatek: mtk-mmsys: Convert to platform remove callback returning void soc/mediatek: mtk-devapc: Convert to platform remove callback returning void soc/loongson: loongson2_guts: Convert to platform remove callback returning void soc/litex: litex_soc_ctrl: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-qmgr: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-npe: Convert to platform remove callback returning void soc/hisilicon: kunpeng_hccs: Convert to platform remove callback returning void ...
