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.
