From: Dmitry Baryshkov Date: Mon, 14 Nov 2022 17:06:29 +0000 (+0300) Subject: dt-bindings: arm-smmu: Add generic qcom,smmu-500 bindings X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6c84bbd103d85696af9cc0f746c01f9b2847637e;p=linux.git 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.
