From 4c953d03970a39d034ee2c860bbd65f5970aa2ce Mon Sep 17 00:00:00 2001 From: Manasi Navare <manasi.d.navare@intel.com> Date: Mon, 8 Oct 2018 17:23:51 -0700 Subject: [PATCH] drm/dp: Add definitions for eDP Rev 1.4a and 1.4b MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VESA eDP 1.4 specification has separate fields defined in EDP_DPCD_REV for eDP 1.4a and 1.4b eDP revisions. This patch defines those. Found this when one of my eDP panels advertises eDP 1.4a (04h) in the EDP_DPCD_REV DPCD field.
