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.
