And it really doesn't matter when the clk driver implementation doesn't use the min/max to clamp the values of the round_rate() call. Is that being done here? I need to double check. I would be more convinced if the implementation was looking at min/max to constrain the rate requested. -- To unsubscribe from this list: send the line "unsubscribe linux-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
