drm/i915/dg2: Tile 4 plane format support
Tile4 in bspec format is 4K tile organized into 64B subtiles with same basic shape as for legacy TileY which will be supported by Display13. v2: - Moved Tile4 associating struct for modifier/display to the beginning(Imre Deak) - Removed unneeded case I915_FORMAT_MOD_4_TILED modifier checks(Imre Deak) - Fixed I915_FORMAT_MOD_4_TILED to be 9 instead of 12 (Imre Deak) v3: - Rebased patch on top of new changes related to plane_caps. - Added static assert to check that PLANE_CTL_TILING_YF matches PLANE_CTL_TILING_4(Nanley Chery) - Fixed naming and layout description for Tile 4 in drm uapi header(Nanley Chery) v4: - Extracted drm_fourcc changes to separate patch(Nanley Chery) Reviewed-by: Imre Deak <imre.deak@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220118115544.15116-3-stanislav.lisovskiy@intel.com
