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 ...

dt-bindings: dma: apple,admac: Add t6020-admac compatible

2025-09-14T19:51:05+00:00

After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,admac" anymore [1]. Use "apple,t8103-admac" as base compatible as it is the SoC the driver and bindings were written for. admac on Apple's M2 Pro/Max/Ultra SoCs is compatible with "apple,t8103-admac" so add its per-SoC compatible with the former as fallback used by the existing driver.

dt-bindings: dma: rz-dmac: Document RZ/G3E family of SoCs

2025-09-02T07:27:20+00:00

The DMAC block on the RZ/G3E SoC is identical to the one found on the RZ/V2H(P) SoC. No driver changes are required, as `renesas,r9a09g057-dmac` will be used as a fallback compatible string on the RZ/G3E SoC.

dt-bindings: dma: qcom: bam-dma: Add missing required properties

2025-08-11T05:22:43+00:00

num-channels and qcom,num-ees are required when there are no clocks specified in the device tree, because we have no reliable way to read them from the hardware registers if we cannot ensure the BAM hardware is up when the device is being probed. This has often been forgotten when adding new SoC device trees, so make this clear by describing this requirement in the schema.
