[PATCH V2 00/12] LP0 entry and exit support for Tegra210

From: Sowjanya Komatineni
Date: Tue May 28 2019 - 19:12:25 EST


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.
