I meant to mention that I'm using this extra patch for my board.

As you can see, it's been a couple of years, and it is not at
all unlikely that the root cause is in these files, and that
there has been changes in the other parts of the sama5d3 code
that I need to pick up.

I will dig into updating these files, and check if that help.

Cheers,
Peter
