Handle only bigjoiner masters in skl_commit_modeset_enables/disables, slave crtcs should be handled by master hooks. Same for encoders. That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave. v2: - Moved skl_pfit_enable, intel_dsc_enable, intel_crtc_vblank_on to intel_enable_ddi, so that it is now finally symmetrical with the disable case, because currently for some weird reason we are calling those from skl_commit_modeset_enables, while for the disable case those are called from the ddi disable hooks. v3: - Create intel_ddi_enable_hdmi_or_sst symmetrical to intel_ddi_post_disable_hdmi_or_sst and move it also under non-mst check. v4: - Fix intel_enable_ddi sequence Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> --- drivers/gpu/drm/i915/display/intel_ddi.c | 45 ++++-- drivers/gpu/drm/i915/display/intel_display.c | 162 +++++++++---------- drivers/gpu/drm/i915/display/intel_display.h | 7 + 3 files changed, 124 insertions(+), 90 deletions(-)
