I just checked - the patches I posted apply cleanly against
linux-linaro-2.6.36. Patch 3 has some line offsets, but otherwise
applies cleanly. EHCI works on Panda after applying these
patches, however I didn't get a chance to check if EHCI on
OMAP3 is still working.
The series (against v2.6.37-rc2) is available here:
in the omap4-ehci-upstream-v1 branch.
