@JakeStevens you did not update the CMakeLists.txt just the buck system. But feel free to proceed. I will update the CMakeLists afterwards.

Do you need to enable/disable the clock gating feature?

[JakeStevens]

I explicitly only updated BUCK, to keep it default OFF for the main, open source entry point. We can update the CMake too if you want to move to default ON for the main build
