Ah, that makes sense - I'd parsed what you wrote as meaning that the first time a stream was configured we'd pick a clock rate and then on any subsequent stream configuration we'd constrain to something that matched the clock rate. I hadn't realised you only meant stream lifetimes rather than system lifetime. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
