Merge tag 'soc-drivers-6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull more SoC driver updates from Arnd Bergmann:
 "These updates came a little late, or were based on a later 6.18-rc tag
  than the others:

   - A new driver for cache management on cxl devices with memory shared
     in a coherent cluster. This is part of the drivers/cache/ tree, but
     unlike the other drivers that back the dma-mapping interfaces, this
     one is needed only during CPU hotplug.

   - A shared branch for reset controllers using swnode infrastructure

   - Added support for new SoC variants in the Amlogic soc_device
     identification

   - Minor updates in Freescale, Microchip, Samsung, and Apple SoC
     drivers"
