2025-02-27platform: cznic: CZNIC_PLATFORMS should depend on ARCH_MVEBUGeert Uytterhoeven
[ Upstream commit dd0f05b98925111f4530d7dab774398cdb32e9e3 ] CZ.NIC's Turris devices are based on Marvell EBU SoCs. Hence add a dependency on ARCH_MVEBU, to prevent asking the user about these drivers when configuring a kernel that cannot run on an affected CZ.NIC Turris system.

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The driver updates seem larger this time around, with changes is many of the SoC specific drivers, both the custom drivers/soc ones and the closely related subsystems (memory, bus, firmware, reset, ...). The at91 platform gains support for sam9x7 chips in the soc and power management code. This is the latest variant of one of the oldest still supported SoC families, using the ARM9 (ARMv5) core. As usual, the qualcomm snapdragon platform gets a ton of updates in many of their drivers to add more features and additional SoC support. Most of these are somewhat firmware related as the platform has a number of firmware based interfaces to the kernel. A notable addition here is the inclusion of trace events to two of these drivers. Herve Codina and Christophe Leroy are now sending updates for drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC and Arm specific platforms and has previously been problematic to maintain. The first update here contains support for newer PowerPC variants and some cleanups. The turris mox firmware driver has a number of updates, mostly cleanups. The Arm SCMI firmware driver gets a major rework to modularize the existing code into separately loadable drivers for the various transports, the addition of custom NXP i.MX9 interfaces and a number of smaller updates. The Arm FF-A firmware driver gets a feature update to support the v1.2 version of the specification. The reset controller drivers have some smaller cleanups and a newly added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs. The memory controller drivers get some cleanups and refactoring for Tegra, TI, Freescale/NXP and a couple more platforms. Finally there are lots of minor updates to firmware (raspberry pi, tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic, mediatek) drivers and their DT bindings" * tag 'soc-drivers-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (212 commits) firmware: imx: remove duplicate scmi_imx_misc_ctrl_get() platform: cznic: turris-omnia-mcu: Fix error check in omnia_mcu_register_trng() bus: sunxi-rsb: Simplify code with dev_err_probe() soc: fsl: qe: ucc: Export ucc_mux_set_grant_tsa_bkpt soc: fsl: cpm1: qmc: Fix dependency on fsl_soc.h dt-bindings: arm: rockchip: Add rk3576 compatible string to pmu.yaml soc: fsl: qbman: Remove redundant warnings soc: fsl: qbman: Use iommu_paging_domain_alloc() MAINTAINERS: Add QE files related to the Freescale QMC controller soc: fsl: cpm1: qmc: Handle QUICC Engine (QE) soft-qmc firmware soc: fsl: cpm1: qmc: Add support for QUICC Engine (QE) implementation soc: fsl: qe: Add missing PUSHSCHED command soc: fsl: qe: Add resource-managed muram allocators soc: fsl: cpm1: qmc: Introduce qmc_version soc: fsl: cpm1: qmc: Rename SCC_GSMRL_MODE_QMC soc: fsl: cpm1: qmc: Handle RPACK initialization soc: fsl: cpm1: qmc: Rename qmc_chan_command() soc: fsl: cpm1: qmc: Introduce qmc_{init,exit}_xcc() and their CPM1 version soc: fsl: cpm1: qmc: Introduce qmc_init_resource() and its CPM1 version soc: fsl: cpm1: qmc: Re-order probe() operations ...
