From d4877cf2293f5463f531769fd12300cb3417c778 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 4 Dec 2009 16:56:37 -0500 Subject: drm/radeon/kms: enable hpd support This enabled interrupt driven hpd support for all radeon chips. Assuming the hpd pin is wired up correctly, the driver will generate uevents on digital monitor connect and disconnect and retrain DP monitors automatically.
