[Bug 608279] Re: i2c support for edid on armel

[Mathieu Poirier]

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.

mpoirier at beagle:~$ sudo modprobe eeprom
mpoirier at beagle:~$ decode-edid 3
decode-edid: decode-edid version 1.1
parse-edid: parse-edid version 2.0.0
parse-edid: EDID checksum passed.
