/*
* 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).
