Is beagle-xM using DSI? Because here the LILLY-A83X board is not. The clock registers are all fine now as before the dt clock conversion patches. I suppose you are using current linus tree. I tested 'next' but didn't get DSS working. I guessed that it would have something to do with early DSS DT integration issues. I'll rebase my current dt board support patchset for LILLY-A83X to current linus tree and investigate DSS further. Thanks -- Christoph
