[PATCH V1 00/12] LP0 entry and exit support for Tegra210

[Sowjanya Komatineni]

This patch series includes Tegra210 deepsleep or LP0 support with
deep sleep exit through RTC alarm wake and power button wake events.

This series also includes save and restore of PLLs, clocks, OSC contexts
for basic LP0 exit.

This patch series is doesn't support for 100% suspend/resume to fully
functional state and we are working on some more drivers suspend and
resume implementations.

Re: [PATCH V1 00/12] LP0 entry and exit support for Tegra210

[Billy Laws]

Hi,
By the looks of this you configure wake events but the pmc driver
still only configures lp1, which is the same as linux 4 tegra 4.4+
which also doesn't support lp0, if its selected in dts it'll just
change it to LP1/SC7 (both have same code path and neither set any lp0
stuff trm says). What confuses me further is that l4t and this
ptachset both configure wake events, which I think should only work in
LP0 and not LP1 and yet neither have lp0 entry code for t210. I also
looked at ATF, whis sets the flags to wake the cpu on interrupts,
which would suggest that it only supports lp1 (in deep sleep I dont
think them flags would work). Am I missing some important detail here?
Two other things, will you be adding full lp0 in later patchets and
will they use the bpmp or not?

There doesn't seem to be support for waking up from a power button
press. Is that in a patch that you didn't send out yet, or are you still
working on that?

The recipient list on this is very trimmed. I'm not sure if this was on
purpose. I'm fine if you want to keep it that way until things settle
down a bit, but eventually the subsystem maintainers will need to see
these, so make sure to Cc them when you think the patches are ready.
