I tried using assigned-parents and it works fine.

The issue you mentioned above doesn't apply in our case, because
we have two different devices for "dsi" and "dsi_phy". dsi_phy is the
clock provider here and dsi is the one that wants to assign clocks.

If there was only one dsi device representing both DSI and PHY, then
we'd hit the condition you mentioned.

Thanks,
