Somebody in the thread at some point said:
| It did work though. OK. I know the problem. My bad. My understanding
| that the pmu will be put to standby when we suspend is fundamentally
Auto really needs to stay up, it's the source of the "always on" IO_3V3
and that's the source of any high levels on the CPU GPIO during suspend.
| That's brings one question to my mind. Why do we need to save the
| registers that don't "survive" standby (a comment in pcf50633_suspend
| says so), if we are not going into standby at all ? Please explain.
It's a good question... those i2c actions are pretty slow, if we can
abandon them it's good.
If you're looking in there you might find what happens to the CPU core
voltage regulator during our suspend interesting too if you think about
