From 966a08c293cb9290d3fe932961404e87b3f81327 Mon Sep 17 00:00:00 2001 From: Sumit Garg Date: Thu, 22 Jan 2026 17:40:40 +0530 Subject: [PATCH] dt-bindings: display: msm: qcm2290-mdss: Fix iommus property Fix IOMMU DT propety for display via dropping SMMU stream IDs which relates to secure context bank. Assigning Linux kernel (HLOS) VMID to secure context bank stream IDs is incorrect. The maximum value for iommus property is updated accordingly. These DT bindings changes should be backwards compatible.
