drm/i915: Make sure DPLL is enabled when kicking the power sequencer on VLV/CHV
The power seqeuencer kick procedure requires the DPLL to be running in order to complete successfully. In case the DPLL isn't currently running when we need to kick the power seqeuncer enable it temporarily. This can happen eg. during ->detect() when the pipe is not already active. To avoid needlessly duplicating the DPLL programming re-use the already existing functions by passing a temporary pipe config to them instead of having them consult the current pipe config at crtc->config. v2: Introduce vlv_force_pll_{on,off}() (Daniel) v3: Rebase due to drm_crtc vs. intel_crtc changes Fix a typo in commit msg (checkpatch) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> (v1) [danvet: Appease checkpatch.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
