Pull SoC driver updates from Arnd Bergmann: "Lots of platform specific updates for Qualcomm SoCs, including a new TEE subsystem driver for the Qualcomm QTEE firmware interface. Added support for the Apple A11 SoC in drivers that are shared with the M1/M2 series, among more updates for those. Smaller platform specific driver updates for Renesas, ASpeed, Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale SoCs. Driver updates in the cache controller, memory controller and reset controller subsystems. SCMI firmware updates to add more features and improve robustness. This includes support for having multiple SCMI providers in a single system. TEE subsystem support for protected DMA-bufs, allowing hardware to access memory areas that managed by the kernel but remain inaccessible from the CPU in EL1/EL0" * tag 'soc-drivers-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (139 commits) soc/fsl/qbman: Use for_each_online_cpu() instead of for_each_cpu() soc: fsl: qe: Drop legacy-of-mm-gpiochip.h header from GPIO driver soc: fsl: qe: Change GPIO driver to a proper platform driver tee: fix register_shm_helper() pmdomain: apple: Add "apple,t8103-pmgr-pwrstate" dt-bindings: spmi: Add Apple A11 and T2 compatible serial: qcom-geni: Load UART qup Firmware from linux side spi: geni-qcom: Load spi qup Firmware from linux side i2c: qcom-geni: Load i2c qup Firmware from linux side soc: qcom: geni-se: Add support to load QUP SE Firmware via Linux subsystem soc: qcom: geni-se: Cleanup register defines and update copyright dt-bindings: qcom: se-common: Add QUP Peripheral-specific properties for I2C, SPI, and SERIAL bus Documentation: tee: Add Qualcomm TEE driver tee: qcom: enable TEE_IOC_SHM_ALLOC ioctl tee: qcom: add primordial object tee: add Qualcomm TEE driver tee: increase TEE_MAX_ARG_SIZE to 4096 tee: add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF tee: add TEE_IOCTL_PARAM_ATTR_TYPE_UBUF tee: add close_context to TEE driver operation ...

Arm SCMI updates/fixes for v6.18 These SCMI changes bring a mix of improvements, fixes, and cleanups: 1. Device Tree bindings - allow multiple SCMI instances by suffixing node names (Nikunj Kela). 2. Code hardening - constify both scmi_{transport,voltage_proto}_ops so they reside in read-only memory (Christophe JAILLET). 3. VirtIO transport initialization - set DRIVER_OK before SCMI probing to prevent potential stalls; while recent rework removes the practical risk, this ensures correctness (Junnan Wu). 4. Quirk handling - fix a critical bug by preventing writes to string constants, avoiding faults in read-only memory (Johan Hovold). 5. i.MX SCMI MISC protocol - extend support to discover board info, retrieve configuration and build data, and document the new MISC_BOARD_INFO command; all handled gracefully if unsupported (Peng Fan). 6. Logging cleanup - simplify device tree node name logging by using the %pOF format to print full paths (Krzysztof Kozlowski). * tag 'scmi-updates-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Simplify printks with pOF format firmware: arm_scmi: imx: Discover MISC board info from the system manager firmware: arm_scmi: imx: Support retrieving MISC protocol configuration info firmware: arm_scmi: imx: Discover MISC build info from the system manager firmware: arm_scmi: imx: Add documentation for MISC_BOARD_INFO firmware: arm_scmi: quirk: Prevent writes to string constants firmware: arm_scmi: Fix function name typo in scmi_perf_proto_ops struct firmware: arm_scmi: Mark VirtIO ready before registering scmi_virtio_driver firmware: arm_scmi: Constify struct scmi_transport_ops firmware: arm_scmi: Constify struct scmi_voltage_proto_ops dt-bindings: firmware: arm,scmi: Allow multiple instances Link: https://lore.kernel.org/r/20250915101341.2987516-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann

dt-bindings: firmware: arm,scmi: Allow multiple instances

2025-08-21T13:11:55+00:00

Enable multiple SCMI instances by appending an instance-number suffix to the 'scmi' node name. The SCMI spec assumes a single SCMI platform, but in practice its responsibilities may be split across several SCMI platform/server instances. However, only one instance can serve as the system-wide (true) SCMI platform.

Pull SoC driver updates from Arnd Bergmann: "Changes are all over the place, but very little sticks out as noteworthy. There is a new misc driver for the Raspberry Pi 5's RP1 multifunction I/O chip, along with hooking it up to the pinctrl and clk frameworks. The reset controller and memory subsystems have mainly small updates, but there are two new reset drivers for the K230 and VC1800B SoCs, and new memory driver support for Tegra264. The ARM SMCCC and SCMI firmware drivers gain a few more features that should help them be supported across more environments. Similarly, the SoC specific firmware on Tegra and Qualcomm get minor enhancements and chip support. In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an overhaul for code robustness, the Tegra and Qualcomm and NXP drivers grow to support more chips, while the Hisilicon, Mediatek and Renesas drivers see mostly janitorial fixes" * tag 'soc-drivers-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (100 commits) bus: del unnecessary init var soc: fsl: qe: convert set_multiple() to returning an integer pinctrl: rp1: use new GPIO line value setter callbacks soc: hisilicon: kunpeng_hccs: Fix incorrect log information dt-bindings: soc: qcom: qcom,pmic-glink: document Milos compatible dt-bindings: soc: qcom,aoss-qmp: document the Milos Always-On Subsystem side channel dt-bindings: firmware: qcom,scm: document Milos SCM Firmware Interface soc: qcom: socinfo: Add support to retrieve APPSBL build details soc: qcom: pmic_glink: fix OF node leak soc: qcom: spmi-pmic: add more PMIC SUBTYPE IDs soc: qcom: socinfo: Add PM7550 & PMIV0108 PMICs soc: qcom: socinfo: Add SoC IDs for SM7635 family dt-bindings: arm: qcom,ids: Add SoC IDs for SM7635 family firmware: qcom: scm: request the waitqueue irq *after* initializing SCM firmware: qcom: scm: initialize tzmem before marking SCM as available firmware: qcom: scm: take struct device as argument in SHM bridge enable firmware: qcom: scm: remove unused arguments from SHM bridge routines soc: qcom: rpmh-rsc: Add RSC version 4 support memory: tegra: Add Tegra264 MC and EMC support firmware: tegra: bpmp: Fix build failure for tegra264-only config ...

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.

dt-bindings: Correct indentation and style in DTS example

2025-07-29T00:56:29+00:00

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.
