This series enables apps-smmu, the "arm,mmu-500" instance
on sdm845.
Changes since v3:
- Refined the dt binding documentation more to align with
Rob's comments for qcom,smmu-v2 binding documentation [1]
on SoC specific compatibles and state things similar
to qcom,smmu-v2 [2].
Changes since v2:
- Dropped patch for gpu-smmu [3] as the same has been pushed by
Jordan [4] 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.

Yea, once the driver changes are pulled in your tree, I can ask Andy to
pick these.
Thanks

Given that this doesn't touch any of the driver code, please take this via
the Andy and arm-soc.

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
