From: Jordan Crouse Date: Mon, 9 Nov 2020 18:47:27 +0000 (-0700) Subject: dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a29bbb0861f487a5e144dc997a9f71a36c7a2404;p=linux.git 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.
