From 14e9a138dd020e234bbbecdbcf4d68eabfe3641e Mon Sep 17 00:00:00 2001 From: Bibek Kumar Patro Date: Tue, 20 Jan 2026 20:41:05 +0530 Subject: [PATCH] iommu/arm-smmu-qcom: Restore ACTLR settings for MDSS on sa8775p The ACTLR configuration for the sa8775p MDSS client was inadvertently dropped while reworking the commit f91879fdf70b ("iommu/arm-smmu-qcom: Add actlr settings for mdss on Qualcomm platforms"). Without this entry, the sa8775p MDSS block does not receive the intended default ACTLR configuration. Restore the missing compatible entry so that the platform receives the expected behavior.
