Merge tag 'arm-soc-drivers-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

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"
