Hello,
I was spending quite some time recently trying to hunt down CPU-suspend
bug on Tegra30 SoC and in the end it was nailed. During that time I
realized that the CPU Idle drivers could get some polish and gain new
features, thus that's what this series does:
1. Unifies Tegra20/30/114 drivers into a single driver and moves it out
into common drivers/cpuidle/ directory.
2. Enables CPU cluster power-down idling state on Tegra30.
3. Removes CPUIDLE_FLAG_TIMER_STOP from all of the states since that
flag is not relevant anymore.
In the end there is a quite nice clean up of the Terga CPUIDLE driver(s)
and of the Tegra's arch code in general. Please review, thanks!
