This series enables apps-smmu, the "arm,mmu-500" instance on sdm845. Series tested on SDM845 MTP device with related smmu patch series [1], and necessary config change, besides one hack to keep LDO14 in LPM mode to boot things up (see the commit in the test branch). The tested branch is available at [2]. Changes since v3: - Refined the dt binding documentation more to align with Rob's comments for qcom,smmu-v2 binding documentation [3] on SoC specific compatibles and state things similar to qcom,smmu-v2 [4]. Changes since v2: - Dropped patch for gpu-smmu [5] as the same has been pushed by Jordan [6] after incorporating the dt binding update. - Updated binding doc to include valid value for '<soc>' in "qcom,<soc>-smmu-500" compatible string. Changes since v1: - Addressed Rob's review comments by adding a SoC specific compatible. Have added a new dt-bindings patch for this. - Updated node name to 'iommu'. - Addressed Doug's review comment about removing status property from smmu's nodes, as smmu is either present on the soc or not. Enabling it is not a board-level decision.
