power: wakelock: Print active wakelocks when has_wake_lock() is called

2010-02-20T01:03:09+00:00

When DEBUG_SUSPEND is enabled print active wakelocks when we check
if there are any active wakelocks.

In print_active_locks(), print expired wakelocks if DEBUG_EXPIRE is enabled

PM: earlysuspend: Removing dependence on console.

2010-02-04T05:27:08+00:00

Rather than signaling a full update of the display from userspace via a
console switch, this patch introduces 2 files int /sys/power,
wait_for_fb_sleep and wait_for_fb_wake.  Reading these files will block
until the requested state has been entered.  When a read from
wait_for_fb_sleep returns userspace should stop drawing.  When
wait_for_fb_wake returns, it should do a full update.  If either are called
when the fb driver is already in the requested state, they will return
immediately.

PM: wakelock: Abort task freezing if a wake lock is held.

2010-02-04T05:27:06+00:00

Avoids a problem where the device sometimes hangs for 20 seconds
before the screen is turned on.

PM: Add user-space wake lock api.

2010-02-04T05:27:05+00:00

This adds /sys/power/wake_lock and /sys/power/wake_unlock.
Writing a string to wake_lock creates a wake lock the
first time is sees a string and locks it. Optionally, the
string can be followed by a timeout.
To unlock the wake lock, write the same string to wake_unlock.

PM: Enable early suspend through /sys/power/state

2010-02-04T05:27:05+00:00

If EARLYSUSPEND is enabled then writes to /sys/power/state no longer
blocks, and the kernel will try to enter the requested state every
time no wakelocks are held. Write "on" to resume normal operation.

PM: Implement early suspend api

PM: wakelocks: Use seq_file for /proc/wakelocks so we can get more than 3K of stats.
