#     Merge tag 'arm-soc-omap-genpd-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
#     
#     Pull ARM SoC OMAP GenPD updates from Arnd Bergmann:
#      "These are additional updates for the power domain support on OMAP,
#       moving to an implementation based on device tree information instead
#       of SoC specific code. This is the latest step in the ongoing process
#       for moving code out of arch/arm/mach-omap2.
#     
#       I kept this separate from the other driver changes since it touches
#       code in multiple areas"
