    We have this usecase in the Ux500. See these patches:
    http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6829/1
    http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6830/1

    Alas, it's not yet merged for the old boardfile world usecase, and
    causing us problems to drive our hardware already.

    Yours,
    Linus Walleij
