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 reverese engineering.) |
44 | * |
45 | * TODO: |
46 | * Make it handle more models. |
47 | * Figure out why the interrupt mode doesn't work. |
