Merge tag 'soc-drivers-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "This is the usual mix of updates for drivers that are used on (mostly
  ARM) SoCs with no other top-level subsystem tree, including:

   - The SCMI firmware subsystem gains support for version 3.2 of the
     specification and updates to the notification code

   - Feature updates for Tegra and Qualcomm platforms for added hardware
     support

   - A number of platforms get soc_device additions for identifying
     newly added chips from Renesas, Qualcomm, Mediatek and Google

   - Trivial improvements for firmware and memory drivers amongst
     others, in particular 'const' annotations throughout multiple
     subsystems"
