Subject: [PATCH v2 05/10] drm/i915: Unduplicate CHV pre-encoder enabling phy logic
Date: Wed, 13 Apr 2016 20:47:48 +0300 [thread overview]
Message-ID: <1460569673-13694-6-git-send-email-ander.conselvan.de.oliveira@intel.com> (raw)
In-Reply-To: <1460569673-13694-1-git-send-email-ander.conselvan.de.oliveira@intel.com>
The only difference between the DP and HDMI versions was the lane count.
Since lane_count is now set appropriately for HDMI too, get rid of the
duplication and move this to intel_dpio_phy.c
v2: Don't move comments about 2nd common lane staying alive. (Ville)
