Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features" * tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (122 commits) firmware: turris-mox-rwtm: Initialize completion before mailbox firmware: turris-mox-rwtm: Fix checking return value of wait_for_completion_timeout() firmware: turris-mox-rwtm: Do not complete if there are no waiters MAINTAINERS: drop riscv list from cache controllers platform: cznic: turris-omnia-mcu: fix Kconfig dependencies bus: sunxi-rsb: Constify struct regmap_bus soc: sunxi: sram: Constify struct regmap_config platform: cznic: turris-omnia-mcu: Depend on WATCHDOG platform: cznic: turris-omnia-mcu: Depend on OF soc: samsung: exynos-pmu: add support for PMU_ALIVE non atomic registers arm64: stm32: enable scmi regulator for stm32 firmware: qcom: tzmem: blacklist more platforms for SHM Bridge soc: qcom: wcnss: simplify with cleanup.h soc: qcom: pdr: simplify with cleanup.h soc: qcom: ocmem: simplify with cleanup.h soc: qcom: mdt_loader: simplify with cleanup.h soc: qcom: llcc: simplify with cleanup.h firmware: qcom: tzmem: simplify returning pointer without cleanup soc: qcom: socinfo: Add PM6350 PMIC arm64: dts: renesas: rz-smarc: Replace fixed regulator for USB VBUS ...
