Merge tag 'drivers-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are updates for drivers that are tied to a particular SoC,
  including the correspondig device tree bindings:

   - A couple of reset controller changes for unisoc, uniphier, renesas
     and zte platforms

   - memory controller driver fixes for omap and tegra

   - Rockchip io domain driver updates

   - Lots of updates for qualcomm platforms, mostly touching their
     firmware and power management drivers

   - Tegra FUSE and firmware driver updateѕ

   - Support for virtio transports in the SCMI firmware framework

   - cleanup of ixp4xx drivers, towards enabling multiplatform support
     and bringing it up to date with modern platforms

   - Minor updates for keystone, mediatek, omap, renesas"
