L138/DA850 USB support in mainline?

[Brian Niebuhr]

What is the current level of support for USB on L138/DA850 in the
mainline kernel?  A similar question was asked here:

http://linux.davincidsp.com/pipermail/davinci-linux-open-source/2011-Jul
y/023201.html

but not really answered.  I'm curious because TI's site at:

http://processors.wiki.ti.com/index.php/DaVinci_GIT_Linux_Kernel

seems to suggest that USB is still not there, but from reading forum
posts it seems as if people are using USB on L138/DA850 with mainline
kernels.  

We are currently using a TI release, but I would like to migrate to a
mainline version.  USB appears to be the only questionable feature at
this point.  Can anyone clarify what support might be missing before I
take the time to make the jump, only to find out that it's not going to
work anyway?  I don't mind doing some work to glue pieces together, but
if major functionality is missing, it would be nice to know beforehand.

Thanks for the help!

Brian
