From ce22c320b8cad000f1b82da6e03848d59c5cf215 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sun, 1 Jul 2012 15:31:04 +0200 Subject: [PATCH] drm/i915/sdvo: convert to encoder disable/enable Similar to crt, this doesn't convert the dpms functions. Also similar to crt, we don't switch of the display pipe for the intermediate modes, only DPMS_OFF is truely off.
