Merge tag 'soc-drivers-6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull more SoC driver updates from Arnd Bergmann: "These updates came a little late, or were based on a later 6.18-rc tag than the others: - A new driver for cache management on cxl devices with memory shared in a coherent cluster. This is part of the drivers/cache/ tree, but unlike the other drivers that back the dma-mapping interfaces, this one is needed only during CPU hotplug. - A shared branch for reset controllers using swnode infrastructure - Added support for new SoC variants in the Amlogic soc_device identification - Minor updates in Freescale, Microchip, Samsung, and Apple SoC drivers" * tag 'soc-drivers-6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) soc: samsung: exynos-pmu: fix device leak on regmap lookup soc: samsung: exynos-pmu: Fix structure initialization soc: fsl: qbman: use kmalloc_array() instead of kmalloc() soc: fsl: qbman: add WQ_PERCPU to alloc_workqueue users MAINTAINERS: Update email address for Christophe Leroy MAINTAINERS: refer to intended file in STANDALONE CACHE CONTROLLER DRIVERS cache: Support cache maintenance for HiSilicon SoC Hydra Home Agent cache: Make top level Kconfig menu a boolean dependent on RISCV MAINTAINERS: Add Jonathan Cameron to drivers/cache and add lib/cache_maint.c + header arm64: Select GENERIC_CPU_CACHE_MAINTENANCE lib: Support ARCH_HAS_CPU_CACHE_INVALIDATE_MEMREGION soc: amlogic: meson-gx-socinfo: add new SoCs id dt-bindings: arm: amlogic: meson-gx-ao-secure: support more SoCs memregion: Support fine grained invalidate by cpu_cache_invalidate_memregion() memregion: Drop unused IORES_DESC_* parameter from cpu_cache_invalidate_memregion() dt-bindings: cache: sifive,ccache0: add a pic64gx compatible MAINTAINERS: rename Microchip RISC-V entry MAINTAINERS: add new soc drivers to Microchip RISC-V entry soc: microchip: add mfd drivers for two syscon regions on PolarFire SoC dt-bindings: soc: microchip: document the simple-mfd syscon on PolarFire SoC ...

+ The AHB/AXI peripherals on the PolarFire SoC have reset support, so
+ from CLK_ENVM to CLK_CFM. The reset consumer should specify the
+ desired peripheral via the clock ID in its "resets" phandle cell.
