This series is for Tegra210 SC7 entry/exit along with clocks and pinctrl 
suspend resume needed for Tegra210 basic sc7 entry and exit.

This includes pinctrl, pmc changes, clock-tegra210 driver changes all 
w.r.t Tegra210 platforms specific.

Suspend/resume support for other Tegras will be in separate patch series.


thanks
