Merge tag 'arm-multiplatform-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARMv4T/v5 multiplatform support from Arnd Bergmann:
 "This series has been 12 years in the making, it mostly finishes the
  work that was started with the founding of Linaro to clean up platform
  support in the kernel.

  The largest change here is a cleanup of the omap1 platform, which is
  the final ARM machine type to get converted to the common-clk
  subsystem. All the omap1 specific drivers are now made independent of
  the mach/*.h headers to allow the platform to be part of a generic
  ARMv4/v5 multiplatform kernel.

  The last bit that enables this support is still missing here while we
  wait for some last dependencies to make it into the mainline kernel
  through other subsystems.

  The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
  at the point of allowing multiplatform kernels, this work gets
  completed here along with a few additional cleanup. At the same time,
  the s3c24xx and s3c64xx are now deprecated and expected to get removed
  in the future.

  The PXA and OMAP1 bits are in a separate branch because of
  dependencies. Once both branches are merged, only the three Intel
  StrongARM platforms (RiscPC, Footbridge/NetWinder and StrongARM1100)
  need separate kernels, and there are no plans to include these"
