Hi,

The auto sleep feature is now in mainline but a very few drivers have been modified (wake up sources and events) to use auto sleep feature. 

I saw a commit 

commit a180c0d659f604568637336a00c0c3ca2f7b094a

    staging: android-alarm: Switch from wakelocks to wakeup sources
    
    In their current AOSP tree, the Android in-kernel wakelock
    infrastructure has been reimplemented in terms of wakeup
    sources:
    http://git.linaro.org/gitweb?p=people/jstultz/android.git;a=commitdiff;h=e9911f4efdc55af703b8b3bb8c839e6f5dd173bb
    
    The Android alarm driver currently has stubbed out calls
    to wakelock functionality. So this patch simply converts
    the stubbed out wakelock calls to wakeup source calls, and
    removes the empty wakelock macros


Is auto sleep feature currently being tested or are there any plans to move all the drivers to use both the wakelock mechanism and autosleep?

Thanks & Regards
