This patch series includes Tegra210 deepsleep/LP0 support with deep sleep exit through RTC alarm wake and power button wake events. Note: Wake on power button is through gpio-keys node in device tree. This series also includes save and restore of PLLs, clocks, OSC contexts for basic LP0 exit. This patch series doesn't support 100% suspend/resume to allow fully functional state upon resume and we are working on some more drivers suspend and resume implementations. [V2] : V1 feedback fixes Patch 0002: This version still using syscore. Thierry suggest not to use syscore and waiting on suggestion from Linux Walleij for any better way of storing current state of pins before suspend entry and restoring them on resume at very early stage. So left this the same way as V1 and will address once I get more feedback on this. Also need to findout and implement proper way of forcing resume order between pinctrl and gpio driver.
