Looking more through the registers... GPIO banks seem to be listed in cm_idlest_per. You mentioned that they should be automatically controlled? Does that still work when they are exported to the userspace? pavel@n900:~$ ls /sys/class/gpio/ export gpio177 gpio73 gpio75 gpiochip128 gpiochip32 gpiochip64 unexport gpio157 gpio70 gpio74 gpiochip0 gpiochip160 gpiochip494 gpiochip96 Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
