Thanks for your reply.
What I am referring to is: when system is suspended (can be waked up by power button) I'd think only below are working:
- RAM is in self-refresh mode
- wakeup circuit is working (wake up by power button)
- RTC circuit is working
- PMIC provides small current for above circuits
- Touch panel is not a wakeup source.
I used to work on TI OMAP chips + LPDDR2, we achieve <2mA suspend current.
