From a29bbb0861f487a5e144dc997a9f71a36c7a2404 Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Mon, 9 Nov 2020 11:47:27 -0700 Subject: dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU Every Qcom Adreno GPU has an embedded SMMU for its own use. These devices depend on unique features such as split pagetables, different stall/halt requirements and other settings. Identify them with a compatible string so that they can be identified in the arm-smmu implementation specific code.
