[PATCH 4/9] drm/i915: Move bxt_ddi_vswing_sequence() call into intel_ddi_pre_enable() for HDMI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Now that the SKL iboost programming is done from intel_ddi_pre_enable()
for HDMI, let's move the BXT bxt_ddi_vswing_sequence() call there as
well. This makes things look more similar to the DP/eDP case which
is handled in ddi_signal_levels().
