OK. Doing the omap1 sparse IRQ conversion has been on my todo list for quite a while. That should be quite easy to do. Sounds getting rid of the ifdeffery in the shared drivers is a good reason to do it. The tricky part with omap1 from multiarch point of view is the clock framework conversion for multi arch support, at this rate it will be years before we get there :) Regards, Tony -- 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
