I'll try it for testing purposes, however my patches need to be based on linux-omap hopefully there won't be any dependency.

This is a bit unexpected -- is there really nobody currently booting
Panda using a DT?

Last time I looked, at v3.3 since that's where we're stuck right now,
dts for Panda is still really minimal. But all over the kernel, there's
dt stuff gone in that's not getting tested even with DT boot path. If
it didn't happen inbetweentimes it might be worth trying at the same
time to generate a "maximum dts" that exercises the new goodies.

No. Normally I would have rebased immediately but as I explained in
another post, we are camped at v3.3 until our new contributors make it
to the 3.4-rc1 rendezvous point. Since just the -core and -pm topics
are already >650 patches, and it's > 1400 total, making a throwaway test
rebase when there's other things still to do is too expensive.

Jassi already took a look last week at v3.3 DT status when he generated
a minimal config for mainline LAVA tests for Andrey.
Jassi maybe you can give pure mainline 3.4-rc1 or HEAD a go and identify
what needs sorting for DT boot path.

Can someone on the LT, working with Omar, take some time to dig into what all
is needed to boot mainline with DT support? I'm a little surprised
too that it doesn't
just work out of the box. :/

Right, LT kernels work fine with DT boot, we have done DT boot on OMAP4
since last Autumn. We still need to add at least this for a long time
http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=commitdiff;h=e7f11e8c3a67ca73da27b33814307077ea73f6b5
I don't know if that's all that's required.
Last week we tried v3.3 mainline and it dies in some problem about UART.
Omar, you should look here
http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=summary
use tilt-tracking and omap_5430evm_defconfig
That's workable on 4430, 4460 (and Omap5) with DT boot. We have a race
bug about mmc probe outstanding but we can't reproduce it at the moment.
Otherwise for 4460 it should be running on all cylinders.

The routine tests we do on each monthly release test for device tree
and this test has passed for panda for months now. That is the LT
kernel that may include some DT patches so maybe that explains this?
