Felipe, Can you go through earlier discussion on this patch http://marc.info/?l=linux-omap&m=127979007623260&w=2 I believe these concerns were discussed. I am unable to open the gmane thread (getting 504) - so can't be sure if Hiroshi had referred to same discussion. ~sanjeev > > -- > Felipe Contreras > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
