dt-bindings: interconnect: Add OSM L3 compatible for QCS615 SoC

2025-09-12T10:53:43+00:00

Add Operation State Manager (OSM) L3 interconnect provider binding for QCS615 SoC. As the OSM hardware in QCS615 and SM8150 are same, added a family-level compatible for SM8150 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 ...

One of the BWMON instances on SM8750 requires that its MMIO space is mapped specifically with the nE memory attribute. Allow the nonposted-mmio property which instructs the OS to do so.

dt-bindings: interconnect: Add EPSS L3 compatible for QCS8300 SoC

2025-07-18T14:54:58+00:00

Add Epoch Subsystem (EPSS) L3 interconnect provider binding for QCS8300 SoC. As the EPSS hardware in QCS8300 and SA8775P are same, added a family-level compatible for SA877P SoC. This shared fallback compatible allows grouping of SoCs with similar hardware, reducing the need to explicitly list each variant in the driver match table.
