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

Pull ARM SoC updates from Arnd Bergmann:
 "There are three noteworthy updates for 32-bit arm platforms this time:

   - The Microchip SAMA7 family based on Cortex-A7 gets introduced, a
     new cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5
     based) SoCs.

   - The ixp4xx platform (based on Intel XScale) is finally converted to
     device tree, and all the old board files are getting removed now.

   - The Cirrus Logic EP93xx platform loses support for the old
     MaverickCrunch FPU. Support for compiling user space applications
     was already removed in gcc-4.9, and the kernel support for old
     applications could not be built with clang ias. After confirming
     that there are no remaining users, removing this from the kernel
     seemed better than adding support for unused features to clang.

  There are minor updates to the aspeed, omap and samsung platforms"
