Subject: [PATCH] drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog
Git-commit: 7cc2621f16b644bb7af37987cb471311641a9e56
Patch-mainline: v6.8-rc1
References: git-fixes
Similar to SC8280XP, the misconfigured SAFE logic causes rather
significant delays in __arm_smmu_tlb_sync(), resulting in poor
performance for things such as USB.
Introduce appropriate SAFE values for SC8180X to correct this.
Fixes: f3af2d6ee9ab ("drm/msm/dpu: Add SC8180x to hw catalog")
