From afb21ea63d815d05f6081ee3efef6772a16317eb Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 31 Aug 2016 18:09:04 +0200 Subject: [PATCH] drm: Move a few macros away from drm_crtc.h Now that there's less stuff in there I noticed that I overlooked them. Sprinkle some docs over them while at it.
