It's bad to have the clk framework and interconnect framework control the same RPMh resource without any coordination. The rpmh driver in the kernel doesn't aggregate resources between clients either, so leaving control to clk-rpmh avoids any issues with unused interconnects turning off IP0 behind the back of the clk framework.
