Your patch is setting static dependency between ISS and l3_2.
It's not dynamic dep. Dynamic dep is managed through hardware and they
are not configurable. But with static dep. you can over-ride that behavior
as you have done.

This will impact power since l3_2 can't idle as long as iss clock
domain is active.

I need to check internal code-base but I don't remember this
issue observed so far.
