From: Stanislav Lisovskiy <stanislav.lisovskiy@xxxxxxxxx>
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
- Call intel_crtc_update_active_timings for slave pipes as well
[v5: vsyrjala: Use the name 'pipe_crtc' for the per-pipe crtc pointer
Use consistent style and naming
Protect macro arguments properly
Drop superfluous changes to the modeset sequence,
this now follows the old non-joiner sequence 100%
apart from just looping in places]
