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,
