Rockchip guys,
I'd really appreciate your input on these two patches please.

After running "poweroff", the PMIC restarts the SoC instead of shutting

It seems like the description for those two register bits is swapped.
After changing from DEV_OFF to DEV_OFF_RST, the system can poweroff
correctly.

I think there maybe something wrong makes your machine restart after
"poweroff".
(1) Is your machine attaching charger when you run "poweroff"?
RK818 is hardware designed to auto power on when it detects voltage on
input pins(8,9);
That's the point! Both pins are driven high... thank you!
We will check how we can handle this on our hardware. For now, I will
recall this patch.

Mit freundlichen Grüßen,

(2) If restart, you can dump ON_SOURCE(address: 0xAE) and
OFF_SOURCE(address: 0xAF) in rk808.c probe() to know last power off
reason and currently power on reason;
