The APQ8064 static replicator has no registers to program, so it does not need an APB clock. Remove its RPM_QDSS_CLK reference. Other programmable CoreSight devices keep their clock references.
QDSS clock is not actually the APB one, it's required for the coresight (or to access some of the regs) if I remember correctly.
If so, it might be atclk for clocking the module rather than the register interface. Could you confirm this?
The replicator is just a middle component on the data path. I read that it shares the same clock with other CoreSight components, so it should still be safe to remove the clock from the replicator node, as other components on the path will ensure that the clock is enabled.
Thanks, Leo
