Subject: parse_az6007.pl: Add a parser for FX2 requests
X-Git-Tag: v4l-utils-0.9.0-test1~254
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0dfc0c6585212d9db2745dc29705aa7d4e095916;p=platform%2Fupstream%2Fv4l-utils.git

parse_az6007.pl: Add a parser for FX2 requests

AZ6007 uses Cypress cy7c68013a 8051-based microcontroller. Adds
a parser for it. The parser doesn't cover all registers, but it
shouldn't be hard to add more as things are guessed from logs
inspection.
