From 5f7ab880558240be952b17a5dc0c9ea3805fc5cf Mon Sep 17 00:00:00 2001 From: Pier Luigi Fiorini Date: Fri, 6 Jan 2017 20:04:04 +0100 Subject: EDID parser library Add a support library to parse EDID that will be used by platform plugins. In order to tell the screen manufacturer from the identifier, the parsers reads /usr/share/hwdata/pnp.ids or, if it's missing, uses a lookup table previously generated from that file with a Python script.
