Merge tag 'arm-soc-drivers-5.11' of git://
Pull ARM SoC driver updates from Arnd Bergmann: "There are a couple of subsystems maintained by other people that merge their drivers through the SoC tree, those changes include: - The SCMI firmware framework gains support for sensor notifications and for controlling voltage domains. - A large update for the Tegra memory controller driver, integrating it better with the interconnect framework - The memory controller subsystem gains support for Mediatek MT8192 - The reset controller framework gains support for sharing pulsed resets For Soc specific drivers in drivers/soc, the main changes are - The Allwinner/sunxi MBUS gets a rework for the way it handles dma_map_ops and offsets between physical and dma address spaces. - An errata fix plus some cleanups for Freescale Layerscape SoCs - A cleanup for renesas drivers regarding MMIO accesses. - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains - New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC identification. - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and SDX55. - A rework of the TI AM33xx 'genpd' power domain support to use information from DT instead of platform data - Support for TI AM64x SoCs - Allow building some Amlogic drivers as modules instead of built-in Finally, there are numerous cleanups and smaller bug fixes for Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips, Renesas, and Xilinx SoCs" * tag 'arm-soc-drivers-5.11' of git:// (222 commits) soc: mediatek: mmsys: Specify HAS_IOMEM dependency for MTK_MMSYS firmware: xilinx: Properly align function parameter firmware: xilinx: Add a blank line after function declaration firmware: xilinx: Remove additional newline firmware: xilinx: Fix kernel-doc warnings firmware: xlnx-zynqmp: fix compilation warning soc: xilinx: vcu: add missing register NUM_CORE soc: xilinx: vcu: use vcu-settings syscon registers dt-bindings: soc: xlnx: extract xlnx, vcu-settings to separate binding soc: xilinx: vcu: drop useless success message clk: samsung: mark PM functions as __maybe_unused soc: samsung: exynos-chipid: initialize later - with arch_initcall soc: samsung: exynos-chipid: order list of SoCs by name memory: jz4780_nemc: Fix potential NULL dereference in jz4780_nemc_probe() memory: ti-emif-sram: only build for ARMv7 memory: tegra30: Support interconnect framework memory: tegra20: Support hardware versioning and clean up OPP table initialization dt-bindings: memory: tegra20-emc: Document opp-supported-hw property soc: rockchip: io-domain: Fix error return code in rockchip_iodomain_probe() reset-controller: ti: force the write operation when assert or deassert ...
