| Subject: ARM: dts: exynos: Fix HDMI-HPD line handling on Arndale |
| |
| From: Andrzej Hajda <a.hajda@samsung.com> |
| |
| [ Upstream commit 21cb5a27483a3cfdbcb7508a06a30c0a485e1211 ] |
| |
| 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. |
