Subject: [PATCH 0/5] DT schema changes for HiKey970 PCIe hardware to work

Hi Rob,

After our discussions, I'm opting to submit first the DT bindings for the
Kirin 970 PCIe support.

Patch 1 is there just because patch 2 needs. You already acked on it.

Patch 5 is also there just as an example of the entire stuff added to
the DTS file.

The core of this series are patches 2 to 4. They contain the conversion
of the kirin-pcie.txt file to the DT schema, and adds the needed
bindings.

Currently, it generates some warnings:

   Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml: pcie@...00000: pcie@4,0:compatible: None of ['pciclass,0604'] are valid under the given schema
	From schema: Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.yaml
	
  Documentation/devicetree/bindings/pci/hisilicon,kirin-pcie.example.dt.yaml: pcie@4,0: reset-gpios: [[4294967295, 1, 0]] is too short

Not sure how/where to fix those. Perhaps at the pci-bus.yaml?

Please review.

Thanks!
Mauro
