 Replying to [comment:5 wmb at firmworks.com]:
 > The "General Purpose I/O Register" at offset 0x315c controls the
 directions of the GPIO pins.  Setting a GPIO bit to input mode will
 prevent it from driving the output actively high, and the signal will
 eventually float low.

 I don't touch that register at all.  I use CCIC register 0xb4 - a
 different "general purpose register", which controls the two camera GPIO
 signals (power and reset).  Or, in theory, it controls them.
