It may be a good idea long term, in fact I almost released this tree as
a branch of the OMAP tree instead of Linus' tree.  As I thought about it
though, there's very little shared code between the two trees, so I
assumed it would be more of a burden on the OMAP community.  So in the
end, I decided to wait and see what type of development community
sprouts up around DaVinci and go from there.  If the OMAP community is
interested in absorbing the DaVinci support, I think long-term
maintenance would be easier.

I'm not fixed on one way or the other, and could easily be pursuaded to
rebase the DaVinci tree.  For kicks, I rebased locally, and there's a
patch adding DaVinci support to todays OMAP tree available here:
http://source.mvista.com/~khilman/davinci/

Some existing areas of overlap I can think of off the top of my head:

- CONFIG_DEBUG_LL patch to kernel/printk.c
- AIC23 code: DaVinci has AIC33 and I have a minor patch to support
AIC33
- There's also hack to the 8250.c serial ISR that used to be needed but
is no longer needed on DaVinci.  It seems some mainline fixes have
removed the need for that.  I'm curious if it's still necessary on OMAP.
