Comment(by nicolas.dufresne):
Ok, as I said, the patch does not fix the issue, it hides it. Still, I can
rework this patch to make it cleaner, maybe I could only include the patch
and get rid of the display_onoff rework (which was the original thing I
wanted to submit until I figured-out that it was better to work on latest
kernel)
What the patch currently doe:
- Moves display_onoff into proper state transitions (aside double display
off bug, thanks to ankostis)
- Disable going into deep_sleep (this is tricky since at boot we assume we
are in deep_sleep)
Instead of this patch, we could just add a sys entry to disable (at
runtime) deep sleep of this chip. This way we keep it for devices that are
not affected and with a small shell script we could disable it for affect
devices. As boot is already done when set, we no longer need the obscure
static variable.
(For binary images, I would prefer if someone from OpenMoko choose if it's
worth it and verify that no damage will be cause to the devices.)
