git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Not much changed in the clk framework this time except the clk.h consumer API moved the context saving APIs around to fix a build error in certain configurations. There was a change to the core framework for CLK_OPS_PARENT_ENABLE behavior during registration, but it wrecked existing drivers that didn't expect things to be turned off during clk registration so it got reverted. This cycle is really a large collection of new clk drivers, primarily for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed. Another big change in here is support for automatic hardware clock gating on Samsung SoCs where the clks turn on and off when needed. Ideally more vendors move to this method for better power savings. The highlights are in the updates section below. Beyond all the new drivers we have a bunch of cleanups like converting drivers from divider_round_rate() to divider_determine_rate() and using scoped for each OF child loops. Otherwise it's the usual data fixes and plugging reference leaks, etc. that's all pretty ordinary but not critical enough to fix until the next release. New Drivers: - Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and video clk controllers - Qualcomm SM8750 camera clk controllers - Qualcomm MSM8940 and SDM439 global clk controllers - Google GS101 Display Process Unit (DPU) clk controllers - SpacemiT K3 clk controllers - Amlogic t7 clk controllers - Aspeed AST2700 clk controllers Updates: - Convert clock dividers from round_rate() to determine_rate() - Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs - Automatic hardware clk gating on Google GS101 SoCs - Amlogic s4 video clks - CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and RZ/V2N - Expanded Serial Peripheral Interface (xSPI) clocks and resets on Renesas RZ/T21H and RZ/N2H - DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and resets on Renesas RZ/V2N - More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N - CPU frequency scaling on T-HEAD TH1520" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (165 commits) clk: aspeed: Add reset for HACE/VIDEO dt-bindings: clock: aspeed: Add VIDEO reset definition clk: aspeed: add AST2700 clock driver MAINTAINERS: Add entry for ASPEED clock drivers. clk: aspeed: Move the existing ASPEED clk drivers into aspeed subdirectory.

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 ...

2025-12-16dt-bindings: soc: samsung: exynos-pmu: remove syscon for google,gs101-pmuPeter Griffin
Since commit ba5095ebbc7a ("mfd: syscon: Allow syscon nodes without a "syscon" compatible") it is possible to register a regmap without the syscon compatible in the node. Update the bindings for google,gs101-pmu so that the syscon compatible is no longer required. As it isn't really correct to claim we are compatible with syscon (as a mmio regmap created by syscon will not work on gs101). Additionally (with the benefit of hindsight) PMU register writes were never working with a MMIO syscon on gs101, so the ABI break is justified.

Add new constants for choosing the additional USIv1 configuration modes in device tree. Those are further used in the USI driver to figure out which value to write into SW_CONF register. Modify the current USI IP-core bindings to include information about USIv1 and a compatible for exynos8895. In the original bindings commit, protocol mode definitions were named with the version of the supported USI (in this case, V2) with the idea of leaving enough room in the future for other versions of this block. This, however, is not how the modes should be modelled. The modes are not version specific and you should not be able to tell USI which version of a mode to use - that has to be handled in the driver - thus encoding this information in the binding is meaningless. Only one constant per mode is needed, so while we're at it, add new constants with the prefix USI_MODE and mark the old ones as depracated.

2023-12-07dt-bindings: samsung: exynos-pmu: add specific compatible for Tesla FSDKrzysztof Kozlowski
Tesla FSD is a derivative of Samsung Exynos SoC, thus just like the others it reuses several devices from older designs. Historically we kept the old (block's) compatible only. This works fine and there is no bug here, however guidelines expressed in Documentation/devicetree/bindings/writing-bindings.rst state that: 1. Compatibles should be specific. 2. We should add new compatibles in case of bugs or features. Add Tesla FSD compatible specific to be used with an existing fallback.

Pull SoC DT updates from Arnd Bergmann: "About a quarter of the changes are for 32-bit arm, mostly filling in device support for existing machines and adding minor cleanups, mostly for Qualcomm and Samsung based machines. Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from Rockchips that have been around for a while but were lacking kernel support so far: RV1126 is a Vision SoC with an NPU and is used in the Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for TV boxes and so far only comes with a dts for its refernece design. The other 32-bit boards that were added are two ASpeed AST2600 based BMC boards, the Microchip sam9x60_curiosity development board (Armv5 based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53 and i.MX6ULL. On the RISC-V side, there are fewer patches, but a total of ten new single-board computers based on variations of the Allwinner D1/T113 chip, plus one more board based on Microchip Polarfire. As usual, arm64 has by far the most changes here, with over 700 non-merge changesets, among them over 400 alone for Qualcomm. The newly added SoCs this time are all recent high-end embedded SoCs for various markets, each on comes with support for its reference board: - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones - Qualcomm QDU1000/QRU1000 5G RAN platform - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs - TI J784S4 for industrial and automotive applications In total, there are 46 new arm64 machines: - Reference platforms for each of the five new SoCs - Three Amlogic based development boards - Six embedded machines based on NXP i.MX8MM and i.MX8MP - The Mediatek mt7986a based Banana Pi R3 router - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115 (Snapdragon 662) and SM8250 (Snapdragon 865) - Two LTE dongles, also based on MSM8916 - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610), SDM450 and SDM632 - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c) - Nine development boards based on Rockchips RK3588, RK3568, RK3566 and RK3328. - Five development machines based on TI K3 (AM642/AM654/AM68/AM69) The cleanup of dtc warnings continues across all platforms, adding to the total number of changes" * tag 'soc-dt-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (1035 commits) dt-bindings: riscv: correct starfive visionfive 2 compatibles ARM: dts: socfpga: Add enclustra PE1 devicetree dt-bindings: altera: Add enclustra mercury PE1 arm64: dts: qcom: msm8996: align RPM G-Link clock-controller node with bindings arm64: dts: qcom: qcs404: align RPM G-Link node with bindings arm64: dts: qcom: ipq6018: align RPM G-Link node with bindings arm64: dts: qcom: sm8550: remove invalid interconnect property from cryptobam arm64: dts: qcom: sc7280: Adjust zombie PWM frequency arm64: dts: qcom: sc8280xp-pmics: Specify interrupt parent explicitly arm64: dts: qcom: sm7225-fairphone-fp4: enable remaining i2c busses arm64: dts: qcom: sm7225-fairphone-fp4: move status property down arm64: dts: qcom: pmk8350: Use the correct PON compatible arm64: dts: qcom: sc8280xp-x13s: Enable external display arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink arm64: dts: qcom: sc8280xp: Add USB-C-related DP blocks arm64: dts: qcom: sm8350-hdk: enable GPU arm64: dts: qcom: sm8350: add GPU, GMU, GPU CC and SMMU nodes arm64: dts: qcom: sm8350: finish reordering nodes arm64: dts: qcom: sm8350: move more nodes to correct place arm64: dts: qcom: sm8350: reorder device nodes ...
