Apologies for hijacking the thread. We have a series for CoreSight[1] that depends on this series, which I see that, is queued in your driver-core-next. I would like to queue [1] for the next version (as there are other work that depend on this, e.g., [2]). Do you have any recommendations/comments on the proposal ? Are you able to share a stable branch which can be merged to coresight/next and queue the series ontop ? (PS: I haven't queued anything for coresight/next yet). Kind regards Suzuki
