Hi Paul,

I've applied this on top of Kevin's PM branch, along with Kevin's ads7846 fix:
http://www.spinics.net/lists/linux-omap/msg73717.html

I think this has fixed the following warning:
[    0.000000] clockdomain: mpu_clkdm: powerdomain ¬õ`À8ºsÀ does not exist
 
But when I try and suspend I still get the same problems:
# echo mem > /sys/power/state
