drm/i915: Fix skl+ non-scaled pfit modes
Fix skl_update_scaler_crtc() to deal with different scaling modes correctly. The current implementation assumes DRM_MODE_SCALE_FULLSCREEN. Fortunately we don't expose any border properties currently so the code does actually end up doing the right thing (assigning a scaler for pfit). The code does need to be fixed before any borders are exposed. Also we have redundant calls to skl_update_scaler_crtc() in dp/hdmi .compute_config() which can be nuked. They were anyway called before we had even computed the pfit state so were basically nonsense. The real call we need to keep is in intel_crtc_atomic_check(). v2: Deal witrh skl_update_scaler_crtc() in intel_dp_ycbcr420_config() Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200422161917.17389-1-ville.syrjala@linux.intel.com
