 Replying to [comment:3 wmb at firmworks.com]:
 > At the hardware level, we have confirmed via an OFW test that writing 8
 to CaFe register 0x3038 makes the camera light go on, and writing 0 to
 that register makes it go off.  That affects CaFe's GPIO3 signal, which
 enables DOVDD_2.8 to the camera, and also the LED.

 Now this is interesting.  I've never touched that register in the camera
 driver; instead, I use
 the "general purpose register" (b4) which has a pair of bits alleged to
 control the values of the GPIO signals.  I'm now getting the sense that
 this register does not work as I had thought it would.  Time to query
 Marvell.
