However resume still does not work with this patch on top of yesterday's
Linus tree snapshot (SL-C3200, ccc0d38). It seems to go to resume for
~300 milliseconds (orange LED lights for a moment, power consumption
increases) and then runs back to the sleep. It seems that it disables
offline charging, too. When battery cover switch is open it goes to
resume just for ~50 milliseconds (orange LED does not light).

The last Pavel's hack from last week at least fixed resume at cost of
breaking offline charging (and broken serial after resume).
