/*
* Driver for the Apollo Domain keyboard and mouse.
*
* Random notes on the Apollo keyboard :
*
* - Powers up in 'cooked' mode, where the alpha keys generate ascii rather
* than make/break codes. Other keys seem to behave OK though.
*
* - Alt L/R keys generate two-byte sequence :
* make break
* L 0xfe,2 0xfe,3
* R 0xfe,0 0xfe,1
*
* - Mouse activity shows up inline in 4-byte packets introduced with 0xdf.
* Byte 1 is 1MRL0000 where M, R, L are the mouse buttons, and 0 is
* down, 1 is up.
* Byte 2 is 2's complement X movement, +ve to the right.
* Byte 3 is 2's complement Y movement, +ve is up.
*
* - Keyboard recognises commands sent to it, all preceded by 0xff. Commands
* are echoed once sent completely.
*
* 0x00 go to cooked mode.
* 0x01 go to 'raw' (scancode) mode.
* 0x12,0x21 status report as <id1>\r<id2>\r<model>\r followed by 0xff
* and then the cooked/raw status.
* 0x21,0x81 beep on
* 0x21,0x82 beep off
*
* Some version examples :
*
* <3-@> <1-0> <SD-03687-MS> Apollo p/n 007121 REV 00 ('old-style' US layout)
* <3-@> <2-0> <SD-03683-MS> Apollo p/n 007121 REV 01 ('old-style' US layout)
* <3-@> <2-0> <SD-03980-MS> Apollo 3500? keyboard.
* <3-@> <X-X> <RX-60857-HW> HP p/n A1630-82001 R2
* ('new-style' off 425t, US layout),
* also Apollo p/n 014555-002
* ('new-style' off DN5500, US layout).
