I do not have that enabled. Enabling that fixes the USB probing. So that is good, thanks.
It doesn't fix the other problem I mentioned with the vpu pgc nodes though. I do get some extra messages now with this enabled and the 6.1 kernel:
imx-pgc imx-pgc-domain.8: failed to command PGC imx-pgc imx-pgc-domain.8: failed to command PGC imx8m-blk-ctrl 38330000.blk-ctrl: deferred probe timeout, ignoring dependency imx8m-blk-ctrl 38330000.blk-ctrl: error -110: failed to attach power domain "g1" imx8m-blk-ctrl: probe of 38330000.blk-ctrl failed with error -110
