Just to clarify why it's like that, see for example
arch/arm/boot/dts/am33xx.dtsi, and target-module at 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
