[ARM] 5323/1: Remove outdated empeg documentation.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. Signed-off-by: Mike Crowe <mac@mcrowe.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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

8The Kenwood KCA-R6A remote control generates a sequence like the following:
9
10Go low for approx 16T (Around 9000us)
11Go high for approx 8T (Around 4000us)
12Go low for less than 2T (Around 750us)
13
14For 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
19Rather than repeat a signal when the button is held down certain buttons
20generate the following code to indicate repetition.
21
22Go low for approx 16T
23Go high for approx 4T
24Go 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
30The 32 bits are encoded as XxYy where x and y are the actual data values
31while X and Y are the logical inverses of the associated data values. Using
32LSB first yields sensible codes for the numbers.
33
34All codes are of the form b9xx
35
36The numeric keys generate the code 0x where x is the number pressed.
