Hello, This series adds support for CPU frequency scaling on Tegra30 and device tree support that allows to implement thermal throttling and customize available CPU frequencies per-board. The tegra20-cpufreq driver has been re-worked to support that all. Note that Tegra30 support not strictly depends on the clock patches that are under review now, CPUFREQ driver will fail to probe until CCLKG clock will get exposed by the clock driver. Hence this series can be applied independently of the clock patches, CPUFREQ will start to work on Tegra30 once both patchsets will be applied.
