[ARM] 5323/1: Remove outdated empeg documentation.
The documents aren't particularly useful anyway and the hardware in
question has never run anything newer than a v2.2.14 kernel to my
knowledge.

3 | The initial design is to go in your car, but you can use it at home, on a | ||
4 | boat... almost anywhere. The principle is to store CD-quality music using | ||
5 | MPEG technology onto a hard disk in the unit, and use the power of the | ||
6 | embedded computer to serve up the music you want. | ||

8 | The Kenwood KCA-R6A remote control generates a sequence like the following: | ||
9 | |||
10 | Go low for approx 16T (Around 9000us) | ||
11 | Go high for approx 8T (Around 4000us) | ||
12 | Go low for less than 2T (Around 750us) | ||
13 | |||
14 | For each of the 32 bits | ||
15 | Go high for more than 2T (Around 1500us) == 1 | ||
16 | Go high for less than T (Around 400us) == 0 | ||
17 | Go low for less than 2T (Around 750us) | ||
18 | |||
19 | Rather than repeat a signal when the button is held down certain buttons | ||
20 | generate the following code to indicate repetition. | ||
21 | |||
22 | Go low for approx 16T | ||
23 | Go high for approx 4T | ||
24 | Go low for less than 2T | ||
25 | |||
26 | (By removing the <2T from the start of the sequence and placing at the end | ||
27 | it can be considered a stop bit but I found it easier to deal with it at | ||
28 | the start). | ||
29 | |||
30 | The 32 bits are encoded as XxYy where x and y are the actual data values | ||
31 | while X and Y are the logical inverses of the associated data values. Using | ||
32 | LSB first yields sensible codes for the numbers. | ||
33 | |||
34 | All codes are of the form b9xx | ||
35 | |||
36 | The numeric keys generate the code 0x where x is the number pressed. | ||
