2025-02-27drm/i915/display: remove leftover struct drm_i915_private forward declarationsJani Nikula
A number of unused struct drm_i915_private forward declarations have been left behind. Remove them.

2021-10-14drm/i915: Remove pointless extra namespace from dkl/snps buf trans structsVille Syrjälä
The struct itself already has sufficient namespace. No need to duplicate it in the members.

2021-10-04drm/i915: Nuke intel_ddi_hdmi_num_entries()Ville Syrjälä
Since intel_ddi_level() now looks at the buf_trans table there's no point in having intel_ddi_hdmi_num_entries() around. Just roll the necessary bits of locic into intel_ddi_hdmi_level()/intel_ddi_level().

2021-08-13drm/i915/dg2: use existing mechanisms for SNPS PHY translationsJani Nikula
We use encoder->get_buf_trans() in many places, for example intel_ddi_dp_voltage_max(), and the hook was set to some old platform's function for DG2 SNPS PHY. Convert SNPS PHY to use the same translation mechanisms as everything else.
