Merge tag 'arm-drivers-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM driver updates from Arnd Bergmann:
 "The drivers branch for 6.1 is a bit larger than for most releases.

  Most of the changes come from SoC maintainers for the drivers/soc
  subsystem:

   - A new driver for error handling on the NVIDIA Tegra 'control
     backbone' bus.

   - A new driver for Qualcomm LLCC/DDR bandwidth measurement

   - New Rockchip rv1126 and rk3588 power domain drivers

   - DT binding updates for memory controllers, older Rockchip SoCs,
     various Mediatek devices, Qualcomm SCM firmware

   - Minor updates to Hisilicon LPC bus, the Allwinner SRAM driver, the
     Apple rtkit firmware driver, Tegra firmware

   - Minor updates for SoC drivers (Samsung, Mediatek, Renesas, Tegra,
     Qualcomm, Broadcom, NXP, ...)

  There are also some separate subsystem with downstream maintainers
  that merge updates this way:

   - Various updates and new drivers in the memory controller subsystem
     for Mediatek and Broadcom SoCs

   - Small set of changes in preparation to add support for FF-A v1.1
     specification later, in the Arm FF-A firmware subsystem

   - debugfs support in the PSCI firmware subsystem"
