From 183bc362334507512fd76db5f96e452de65092a2 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 14 Nov 2022 20:06:29 +0300 Subject: [PATCH] dt-bindings: arm-smmu: Add generic qcom,smmu-500 bindings Add generic bindings for the Qualcomm variant of the ARM MMU-500. It is expected that all future platforms will use the generic qcom,smmu-500 compat string in addition to SoC-specific and the generic arm,mmu-500 ones. Older bindings are now described as deprecated. Note: I have split the sdx55 and sdx65 from the legacy bindings. They are not supported by the qcom SMMU implementation. I can suppose that they are using the generic implementation rather than the Qualcomm-speicific one. [Add dt-bindings for qcom,smmu-500 for Qcom SoCs].
