      ARM: tegra30: cpuidle: add powered-down state for secondary CPUs · d457ef35
      Joseph Lo 提交于
      This supports power-gated idle on secondary CPUs for Tegra30. The
      secondary CPUs can go into powered-down state independently. When
      CPU goes into this state, it saves it's contexts and puts itself
      to flow controlled WFI state. After that, it will been power gated.
      
      Be aware of that, you may see the legacy power state "LP2" in the
      code which is exactly the same meaning of "CPU power down".
