From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Something has changed in the hardware on LNL/BMG because
HDMI outputs no longer have the extra scanline offset.
I confirmed that MTL still has the old behaviour, which
is a bit weird since both MTL and BMG have display ver 14
vs. LNL is version 20. But can't argue with actual
hardware behaviour.
Ville Syrjälä (3):
drm/i915: Fix scanline_offset for LNL+ and BMG+
drm/i915: Reverse the scanline_offset if ladder
drm/i915: Replace the HAS_DDI() in intel_crtc_scanline_offset() with
specific platform checks
