It may simply be that the pin assignments are the same for these devices, i.e.
they use the same physical pin for controller wakeup. This wouldn't surprise
me at all.

And since the wakeup sequence is sent before actually communicating with the
device over I2C, it seems logical that the ChipOne wakes up and stays on after
the atmel_probe function has been called - even if probe fails afterwards.
