Just to clarify why it's like that, see for example arch/arm/boot/dts/am33xx.dtsi, and target-module@47400000 in that file for the musb controller.
There's a single ti-sysc interconnect target module, but it has multiple devices. There are two musb controler instances, two phy instances and a cppi41 dma instance within a single module.
With sgx, I belive there is only the sgx IP within the ti-sysc interconnect target module. They are still seprate devices with their own control registers.
Regards,
Tony
