From 4573ebe5ec3121dd4e6f3e8f0c5feba01a235251 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 22 Aug 2016 15:54:30 +0300 Subject: [PATCH] drm/omap: poll only connectors where the connect/disconnect can be checked When the connector associated detect callback is not provided, we can not detect if the display is connected or disconnected. These displays do not support hot plug, they are always connected. Let DRM know that connectors w/o detect callback should not be polled.
