This just made me realise, this is also the time where the clocks are
disabled, and we changed our clock implementation in 4.11.
And using the 4.4 DT will keep the old driver...
Did you test in 4.11? If it's also broken, could you try to revert
1f4ce3b6ca79 and 6b48644b1d29 (I'm not sure it's going to be a trivial
revert, but in that order it should work).
