Let's check...

My koelsch-legacy kernel has drivers/sh/pm_runtime.c compiled in.
My koelsch-reference kernel hasn't.

However, under the -reference kernel many MSTP clocks (incl. MSIOF)
seem to be enabled all the time, while under -legacy they are enabled and
disabled on demand.

Gr{oetje,eeting}s,
