From 7be25cce3466809be0b38e62ed6105281cfd7445 Mon Sep 17 00:00:00 2001 From: Harry Wentland Date: Fri, 31 Jul 2015 21:21:08 -0400 Subject: amd/dal: Display Capability Service Reads, parses, caches an enumerates display (sink) capabilities. Uses I2cAux component to read capabilities from the receiver. While parsing the EDID, DCS will call Timing Service to get timing parameters for DMT and CVT EDID timings.
