Any volunteers? :) It requires huge amount of work,

Well, it's actually quite straight forward. With the changes that got merged
to 3.7, pxa3xx platforms boot, and I also ported some pxa specific
peripheral drivers that should work for both 2xx and 3xx. Adding CPU support
for 27x should also just be a matter of some extra lines.

So I would clearly say you should give the DT approach a try first and see
which bits are missing. And I would vote for not taking any new features for
the legacy board support files but just bugfixes.

Fair enough, I'll resend series without USB stuff (so it'll contain
only bugfixes)

I rather wanted to encourage you to work on the PXA2xx DT stuff :)

I'm not refusing to work on PXA2xx DT stuff, just want to get bugfixes in place,
some of them are serious enough (like fixing oops on poweroff)

Please have a quick look at arch/arm/mach-pxa/pxa-dt.c - what it takes
for basic 270 support is just copying the logic that is there already
for the 3xx models.

Sure, but I need to get DT-capable bootloader working on Z2 in first
place, right?

Some parts like the uart, host-mode usb, mmc, gpio-leds, gpio-keys, i2c
etc are already finished and should work instantly. What's missing is
the spi controller and the display, but maybe you can help getting these
done?

What about libertas? I still don't understand how DT handles platform-specific
callbacks like set_power(). And what about pm_power_off hook?
