So the original submission was not correct? You really need to stop sending DTS based on current driver support and focus on proper hardware description. Such things pop up from time to time for Qualcomm and I don't see much of improvement. And we do not talk about some ancient code, predating guidelines, but IPQ5332 upstreamed ~1 year ago.
