dt-bindings: arm: stm32: add required #clock-cells property

2025-08-28T15:43:56Z

On STM32MP25 SoC, the syscfg peripheral provides a clock to the display subsystem through a multiplexer. Since it only provides a single clock, the cell value is 0. Doing so allows the clock consumers to reach the peripheral and gate the clock accordingly.

Merge tag 'soc-dt-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC devicetree updates from Arnd Bergmann: "There are a few new variants of existing chips: - mt6572 is an older mobile phone chip from mediatek that was extremely popular a decade ago but never got upstreamed until now - exynos2200 is a recent high-end mobile phone chip used in a few Samsung phones like the Galaxy S22 - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M (R8A779H0) and used in automotive applications - Tegra264 is a new chip from NVIDIA, but support is fairly minimal for now, and not much information is public about it There are five more chips in a separate branch, as those are new chip families that I merged along with the necessary infrastructure. New board support is not that exciting, with a total of 33 newly added machines here: - Evaluation platforms for the chips above, plus TI am62d2 and Sophgo sg2042 - Six 32-bit industrial boards based on stm32, imx6 and am33 chips, plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and imx95 - Two newly added ASPEED BMC based motherboards, and one that got removed - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit msm8976 SoCs - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1 - A set-top box based on Amlogic meson-gxm Updates for existing machines are spread over all the above families. One notable change here is support for the RP1 I/O chip used in Raspberry Pi 5" * tag 'soc-dt-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (606 commits) riscv: dts: sophgo: fix mdio node name for CV180X riscv: dts: sophgo: sophgo-srd3-10: reserve uart0 device riscv: dts: sophgo: add Sophgo SG2042_EVB_V2.0 board device tree riscv: dts: sophgo: add Sophgo SG2042_EVB_V1.X board device tree dt-bindings: riscv: add Sophgo SG2042_EVB_V1.X/V2.0 bindings riscv: dts: sophgo: add ethernet GMAC device for sg2042 riscv: dts: sophgo: Enable ethernet device for Huashan Pi riscv: dts: sophgo: Add mdio multiplexer device for cv18xx riscv: dts: sophgo: Add ethernet device for cv18xx riscv: dts: sophgo: sg2044: add pmu configuration riscv: dts: sophgo: sg2044: add ziccrse extension riscv: dts: sophgo: add zfh for sg2042 riscv: dts: sophgo: add ziccrse for sg2042 riscv: dts: sophgo: Add xtheadvector to the sg2042 devicetree riscv: dts: sophgo: sg2044: add PCIe device support for SG2044 riscv: dts: sophgo: sg2044: add MSI device support for SG2044 riscv: dts: sophgo: add reset configuration for Sophgo CV1800 series SoC riscv: dts: sophgo: add reset generator for Sophgo CV1800 series SoC dt-bindings: soc: sophgo: Move SoCs/boards from riscv into soc, add SG2000 riscv: dts: sophgo: sg2044: Add missing riscv,cbop-block-size property ...

dt-bindings: Correct indentation and style in DTS example

2025-07-29T00:56:29Z

DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.
