Do you have any insights w.r.t. the first part of my email? Is there any hope of finding out what the actual max speed is of the async bridge, and what the consequences might be of exceeding it? As I said, currently that bridge is being severely overclocked on any omap5 running a mainline kernel at OPP_HIGH, yet no problems are apparent even if I flood the L3 bridge with traffic. Setting the divider to /8 on the other hand hurts MPU-L3 performance badly and L3-heavy use cases may want to avoid it, leaving the choice of either sacrificing cpu speed or just keeping things as it is now and hope for the best.
