shouldn't that be FACTOR(TOP_UNIVPLL_D10, "univpll_d10", "univpll_249p6m", 1, 2), as univpll_249p6m is univpll divided by 5? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
