From 76e5a89c0a01c43b09512da633910dd0d8b398be Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 29 Jun 2012 22:39:33 +0200 Subject: [PATCH] drm/i915: add crtc->enable/disable vfuncs insted of dpms Because that's what we're essentially calling. This is the first step in untangling the crtc_helper induced dpms handling mess we have - at the crtc level we only have 2 states and the magic is just in selecting which one (and atm there isn't even much magic, but on recent platforms where not even the crt output has more than 2 states we could do better).
