This currently works with the legacy platform data still around. To fix this, let's add the interconnect target modules so we can idle the unused interconnect target module on init. Also note that adding the interconnect target module node does not necessarily mean that there is a driver available for the child IP block, or that the child IP block is even functional. In the SGX case, the PowerVR driver is closed source. And McASP on omap4 has at least the TX path disabled and is not supported by the davinci-mcasp driver. For AESS there is old Android 3.4 kernel driver available. For smarflex, we are still probing with platform data and the driver needs more work before we can add the device ip child nodes. And finally, we're not yet using the interconnet ranges. I will be posting separate patches for those later on.
