     34  * The SPIC is used on some Sony Vaios to handle the jog dial and other
     35  * peripherals.
     36  * The protocol used by the SPIC seems to vary wildly among the different
     37  * models, and I've found no documentation.
     38  * This file handles the jog dial on the SRX77 model, and perhaps nothing
     39  * else.
     40  *
     41  * The general way of talking to the SPIC was gleaned from the Linux and
     42  * FreeBSD drivers.  The hex numbers were taken from these drivers (they
     43  * come from reverse engineering.)
     44  *
     45  * TODO:
     46  *   Make it handle more models.
     47  *   Figure out why the interrupt mode doesn't work.
