ENGR00133978 PM: add time sensitive debug function to suspend & resume

2011-04-01T03:33:50+00:00

There was some driver is slow on suspend/resume,
but some embeded system like eReader,Cellphone
are time sensitive,this commit will report the slow
driver on suspend/resume, the default value is 500us(0.5ms)

Also, the threshold can be change by modify
'/sys/power/device_suspend_time_threshold' to change the threshold,
it is in microsecond.

The output is like:

PM: device platform:soc-audio.2 suspend too slow, takes          606.696 msecs
PM: device platform:mxc_sdc_fb.1 suspend too slow, takes         7.708 msecs

the default state of suspend driver is default off,
if you want to debug the suspend time, echo time in
microsecond(u Second) to /sys/powe/device_suspend_time_threshold

eg: I want to know which driver suspend & resume takes
more that 0.5 ms (500 us), you can just :

ehco 500 > /sys/power/device_suspend_time_threshold

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

2011-03-29T20:57:52+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.

2011-03-29T20:57:04+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.
