Same for encoders. That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave. v2: Get rid of master vs slave checks and separation in crtc enable/disable hooks. Use unified iteration cycle for all of those, while enabling/disabling transcoder only for those pipes where its needed(Ville Syrjälä) v3: Move all the intel_encoder_* calls under transcoder code path(Ville Syrjälä) Signed-off-by: Stanislav Lisovskiy --- drivers/gpu/drm/i915/display/intel_ddi.c | 3 +- drivers/gpu/drm/i915/display/intel_display.c | 183 ++++++++++++------- drivers/gpu/drm/i915/display/intel_display.h | 6 + 3 files changed, 121 insertions(+), 71 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_ddi.c b/drivers/gpu/drm/i915/display/intel_ddi.c index 922194b957be2..6c690aefec9d1 100644 --- a/drivers/gpu/drm/i915/display/intel_ddi.c +++ b/drivers/gpu/drm/i915/display/intel_ddi.c @@ -3340,8 +3340,7 @@ static void intel_enable_ddi(struct intel_atomic_state *state, { drm_WARN_ON(state->base.dev, crtc_state->has_pch_encoder);
