Hmm. If you comment out the twl power node, does the omap3-beagle-ab4.dtb
boot normally for you? It should behave the same as current mainline then
with the omap3isp issue.

OK. So for your rev c2 board, does the new omap3-beagle.dtb boot and
work for you?

Yeah. Especially if it makes things worse for omap3-beagle-ab4.dtb.
