Ironically this is one and the same issue, but you're right that it's more major than I made it out to be. See RTCYEARA2. My theory is that to account for more possible year values they needed all 8 bits. That meant that the enable bit needed to move to a different register. ...and once you moved one enable you might as well move them all, I guess. -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
