parse-edid demands binary date, something i2cdump doesn't provide.
I added an additional 'i2c_board_info' structure and tied it to the i2c
'eeprom' driver, which creates the following
/sys/bus/i2c/devices/3-0050/eeprom entry. From there using 'decode-
edid' specifying to scan bus 3 is trivial. Note that decode-edid calls
parse-edid.
mpoir...@beagle:~$ sudo modprobe eeprom
mpoir...@beagle:~$ decode-edid 3
decode-edid: decode-edid version 1.1
parse-edid: parse-edid version 2.0.0
parse-edid: EDID checksum passed.
