I assume there's no particular need to take this for 3.9; it can wait until 3.10? -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

No. There isn't. These clocks aren't used yet because we don't have CPU DVFS.

Unlike Tegra30, Tegra20 does not have a 7.1 divider for the CPU superclk. Remove the clocks related to the divider.
