Merge tag 'arm-multiplatform-5.19-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc 

Pull yet more ARM multiplatform updates from Arnd Bergmann:
 "This is the third and final bit of the multiplatform conversion for
  ARMv5, finishing off OMAP1. One patch enables the common-clk
  interface, and the other ones does the Kconfig change.

  These were waiting on a few dependencies to trickle in for common-clk,
  and the last one of those was in the USB tree"

* tag 'arm-multiplatform-5.19-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
  ARM: omap1: enable multiplatform
  ARM: OMAP1: clock: Convert to CCF
