From 4cbe1bfa27dcc8e757c723f27e5a8e8b5fc32117 Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Fri, 23 May 2014 16:01:43 +0100 Subject: drm: Add 800x600 (SVGA) screen resolution to the built-in EDIDs The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro. Tested new EDID on an aged (and misbehaving) industrial LCD panel; existing EDIDs still pass edid-decode's checksum checks.
