XO-1 can't wake on lid close

[pgf]

when the laptop is in open, in idle suspend, and the lid is closed, the backlight will stay on until the system wakes for some other reason.

the attached patch adds a sysfs node (matching the one implemented for XO-1.5) which lets one enable wake-on-close.

(i should add that the patch is untested.)

note: initial brief testing of "disable_lid.patch" showed it to be insufficient.

Triaging for 10.1.3 .

Paul, do you think you'll have a more complete fix sometime soon, considering 1.75 bringup workload? Is the (insufficient) patch above on the F11 OLPC kernel?

i'd like to look at this again, but it won't be for at least another week, probably more, and my initial testing gave me doubts as to a final fix. no changes have yet gone into git.

if someone else with kernel and geode gpio chops would like to give it a try, i'm happy to cheer from the sidelines.

lid wakeups on XO-1 are now implemented via new /sys/power/wake-on-lid node, which can take the values "always", "open", "close", or "never". implemented in 1edf204d38125e46ae9e45c641f9b7877eec2a5c.

So I take it that combined with powerd-30 we're all sorted? Excellent!

I guess that is the one for #10398 and this ticket. The new powerd is already in the repo, Paul are you doing as well the kernel packages? Or who do we need to ping here?

Is in 354.

recordkeeping: #8137 and #7536 are closed as dups of this bug.

XO-1s no longer wake up on lid open by default in 10.1.3 os354, and turn off the backlight when closed.

The sysfs field is there and can report & be set with the above values. However in practical usage any directly made user changes get reset by powerd to match its' configuration needs on set events.
