By the way, instead of merging this revert I just dropped the commit that this patch is reverting from the controller/qcom branch, please have a look to check if everything is what you expect it to be there.

The plan is to remove the "iommus" property from Qcom PCI binding since we have removed the usage of that property from devicetree [1]. Initially the iommu properties were not documented at all in the binding. But commit, "dt-bindings: PCI: qcom: Add SM8550 compatible" added them to the binding to satisfy dtbs check. But in parallel, the patch removing "iommus" property from dts got merged to qcom tree. So now we have 2 options here: 1. Amend the commit "dt-bindings: PCI: qcom: Add SM8550 compatible" to remove the "iommus" property. 2. I will submit a separate patch removing that property. Lorenzo, let me know what works for you. Sorry for the mess! Confusion happened due to patches getting applied without sync. - Mani [1] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=6340b391e15094575911ab0d96bfff09deadafba > Lorenzo > > > - Mani > > > > > > > > > > So let's revert the commit that just added "iommu-map" to avoid > > > > duplication. > > > > > > > > Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> > > > > --- > > > > Documentation/devicetree/bindings/pci/qcom,pcie.yaml | 2 -- > > > > 1 file changed, 2 deletions(-) > > > > > > > > diff --git a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > > > index 5d236bac99b6..a1318a4ecadf 100644 > > > > --- a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > > > +++ b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > > > @@ -78,8 +78,6 @@ properties: > > > > > > > > dma-coherent: true > > > > > > > > - iommu-map: true > > > > - > > > > interconnects: > > > > maxItems: 2 > > > > > > > > -- > > > > 2.25.1 > > > > > > > > -- > > மணிவண்ணன் சதாசிவம்

This reverts commit 6ebfa40b63ae65eac20834ef4f45355fc5ef6899. "iommu-map" property is already documented in commit ("dt-bindings: PCI: qcom: Add SM8550 compatible") along with the "iommus" property. So let's revert the commit that just added "iommu-map" to avoid duplication.
