I suggest merging this fix for 4.18-rc, and then Roger can rework the
driver so that it works also on OMAP.

omap has its own glue layer for several reasons. If you're talking about
Keystone devices, then okay, I understand. But in that case, this would
mean Keystone is copying the same arguably broken PM domain design from
OMAP and it would be best not to propagate that idea.

Maybe so. I'm not sure what Roger's use case is, but perhaps the omap
glue driver could be used instead.

unlikely. Keystone devices are very different from OMAP family. But
we'll see what Roger says.
