Hmm I suggest git bisect, I'm pretty sure I was using my panda es
with my omap4 DT conversion patches against v3.10-rc1.
In any case, please also test your changes against the current
omap-for-v3.11/cleanup branch that drops omap4 legacy hwmod data for
the parts that should come from DT. If you see some additional issues
with that, we can revert the related parts of the last patch in
omap-for-v3.11/cleanup.

Tony
