I'm hoping there's a more straightforward way. Right now there is no "elegant" way for this, unfortunately. A common way many drivers use is to remember the rate of the first stream, then add it to hw_constraint of the secondary streams. But, this could be also a bit racy (unavoidable due to its design) although practically it seems working.
