Hmm this you might get fixed automatically by configuring the parent interconnect target module to use "ti,sysc-omap4" and adding VIP1 and VIP2 as children to it.
The reason why I suspect it will fix the issue is because with the parent being "ti,sysc-omap4" with "ti,hwmods" being in that parent node too, you automatically get PM runtime refcounting keep the parent active for either child.
Maybe give it a try against today's Linux next and see for example how it was done for musb:
https://patchwork.kernel.org/patch/9978783/
Just use "ti,sysc-omap2" for type1 and "ti,sysc-omap4" for type2.

Tony
