So, it would be good to state explicitly here that all revisions of all omap4 devices are impacted by this errata. The code implies this but for documentation purposes it would be worth stating. Okay, I'll add some extra beef here. -Tero -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
