[PATCH] drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog

2023-11-30 Thread Bjorn Andersson
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")
