From 8bcad9e3a6742f15d3a8569a987b9ccbefeb4f55 Mon Sep 17 00:00:00 2001 From: Lokanadha M R Date: Tue, 28 Apr 2026 15:13:50 +0530 Subject: iommu/arm-smmu-qcom: Add glymur MDSS to ACTLR client table Add qcom,glymur-mdss to the qcom_smmu_actlr_client_of_match[] table to configure the SMMU-500 context bank for the display subsystem (MDSS) on the Glymur platform. The settings disable the next-page prefetcher while keeping macro TLB caching enabled. Without this entry, qcom_smmu_set_actlr_dev() finds no match for the glymur MDSS device and leaves the context bank ACTLR at its reset value.
