Jagan,

Is there anyway you could rebase this onto 5.18-rc1? Marek was having
issues applying patches to a known branch, and it looks like I cannot
enable stuff on Nano without applying a bunch of patches, because this
base lacks the power-domain features on Nano that are present in the
5.18-rc1.

thanks,
