We can than experiment, and we might use the OMAP3 workaro= und for=20 OMAP2 as well. I'll send the v4 series shortly (after testing). --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
