Hmmh, sorry if I missed something? But my understanding and implementation goal is to have MUSB clock enabled only if CONFIG_MUSB is enabled (and not every time). As mentioned above, this will be done later with an USB patch to be sent to USB maintainer. I.e. MUSB clock will be enabled only if it is really needed because CONFIG_MUSB is enabled (by patch to be sent later).
