[v3,3/4] drm/msm/dpu: remove GC and IGC related code from dpu catalog
Commit Message
Gamma Correction (GC) and Inverse Gamma Correction(IGC) is
currently unused. In addition dpu_dspp_sub_blks didn't even have an igc
member describing the block.
Drop related code from the dpu hardware catalog otherwise this becomes a
burden to carry across chipsets in the catalog.
changes in v3:
- drop IGC related code from dpu_hw_catalog too
- update commit text accordingly
