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