From 21cb5a27483a3cfdbcb7508a06a30c0a485e1211 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Thu, 26 Jul 2018 12:12:28 +0200 Subject: ARM: dts: exynos: Fix HDMI-HPD line handling on Arndale HDMI-HPD was set active low, moreover by default pincontrol chip sets pull-down on the pin. As a result HDMI driver assumes TV is always connected regardless of actual state. The patch fixes it.
