    Right now, I'm developing etnaviv in spare time on the Cubox[*], which
    is still primarily running a non-DT kernel.

    It's actually a kernel that I've hacked which is capable of booting
    both DT and non-DT, but even when booted in DT mode, I still require
    much of the arch/arm/mach-dove infrastructure to get things like
    armada-drm, etnaviv and other drivers running. Especially because
    we're missing things like the high-speed clocks (the stuff above the
    tclk domain.) I've not even started to work out how to get that
    into mainline, or how to integrate that with CCF. Quite what can be
    done with the audio patches, I've no idea, that remains a bone of
    contention and stalemate, and currently isn't DT-able. See the list
    of patches at the end of this message...

    It feels today like I'm the only one working on improving Dove support,
    and so it's going to take a _long_ time to move things forward - it's
    likely to take years. I have many demands on my time and I have to
    divide it up between the various aspects.

    Eg, it's taken me a whole year to get the second batch of patches for
    the component helper out the door... most of the time I can't see the
    trees for all the patches I'm carrying.

    * - I'm fed up with waiting for etnaviv to mature; I've been waiting
    two years so far in the hope that others will do the work and finally
    provide everyone with a solution to the closed source userspace blob.
    Consequently, I don't have much time to push Dove stuff forwards right
    now - though it can be argued that etnaviv _is_ pushing Dove forwards.
    Omitting historical galcore and current etnaviv patch sets, I have 115
    patches for Cubox support outstanding.

    Note: some of those 115 patches have been merged during the 4.4 merge
    window (eg, the tda998x changes and armada drm changes) though I won't
    be in a position to know what the new state of affairs are until after
    4.4 has been released - where upon I will (as normal) rebase my entire
    cubox patch set on the next released kernel.
