Thanks for the hint. Oddly enough, I do see some changes, but only in
the order of the lines - and in particular, even though some lines are
moved around, all clocks are still under the same parent clock as
before. Also all frequencies are the same before/after.

Specifically, I see media_mipi_phy1_ref, media_axi and media_apb (along
with their children) being moved up/down, but they are still children
of, respectively, osc_24m, sys_pll2_1000m and sys_pll1_800m.

So I don't see how that could help me figure out some
assigned-clock-rates or assigned-clock-parents settings that are missing
from DT.

Thanks,
Rasmus
