From ffe3640d7cdd38b28b68cb993f8e29f8d20891c5 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 13 Apr 2015 10:57:14 +0300 Subject: [PATCH] drm/edid: add #defines for ELD versions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add ELD versions according to HDA Specification v1.0a. 2 indicates version 2, which supports CEA_Ver 861D or below. Maximum Baseline ELD size of 80 bytes (15 SAD count). 31 indicates an ELD that has been partially populated through implementation specific mean of default programming before an external graphics driver is loaded. Only the field that is called out as "canned" field will be populated, and audio driver should ignore the non "canned" field.
