From: Bjorn Andersson Date: Fri, 1 Dec 2023 00:35:01 +0000 (-0800) Subject: drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7cc2621f16b644bb7af37987cb471311641a9e56;p=linux.git drm/msm/dpu: Add missing safe_lut_tbl in sc8180x catalog 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.
