| 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. |
