From eed45b30cd1423f8dc10b4312700773cac13c1c8 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 4 Dec 2009 14:45:27 -0500 Subject: [PATCH] drm/radeon/kms: get HPD info for connectors This populates the connectors with HPD (Hot Plug Detect) information. This will be used in subsequent patches for automatic digital monitor connect/disconnect handling.
