From d2182a660808d9053a605e3ebc8c46a323ec6e5d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 9 Jan 2015 14:21:14 +0200 Subject: [PATCH] drm/i915: Don't register HDMI connectors for eDP ports on VLV/CHV MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If we determine that a specific port is eDP, don't register the HDMI connector/encoder for it. The reason being that we want to disable HPD interrupts for eDP ports when the display is off, but the presence of the extra HDMI connector would demand the HPD interrupt to remain enabled all the time.
