From 5137c8ca4be8cd54c1bc74bc1f163a57c7871b38 Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Thu, 3 Apr 2014 20:41:03 +0530 Subject: [PATCH] drm/exynos: Read hpd gpio in is_connected callback This patch adds a gpio read of hpd during the is_connected callback. This fixes the case where hdmi is off going into suspend and the cable is plugged in while suspended. In this case, the hpd interrupt does not fire and is_connected will return false.
