From: Daniel Vetter Date: Mon, 2 Jul 2012 07:56:42 +0000 (+0200) Subject: drm/i915: copy&paste drm_crtc_helper_set_mode X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a6778b3cfd7711951d8973286b783bc061281256;p=openwrt%2Fstaging%2Fblogic.git drm/i915: copy&paste drm_crtc_helper_set_mode Together with the static helper functions drm_crtc_prepare_encoders and drm_encoder_disable (which will be simplified in the next patch, but for now are 1:1 copies). Again, no changes beside new names for these functions. Also call our new set_mode instead of the crtc helper one now in all the places we've done so far. v2: Call the function just intel_set_mode to better differentia it from intel_crtc_mode_set which really only does the ->mode_set step of the entire modeset sequence on one crtc. Whereas this function does the global change.
