[PATCH 1/3] dt-bindings: PCI: cdns,cdns-pcie-host: drop redundant msi-parent and pci-bus.yaml

[PATCH 1/3] dt-bindings: PCI: cdns,cdns-pcie-host: drop redundant msi-parent and pci-bus.yaml

[Krzysztof Kozlowski]

The binding reference common cdns-pcie-host.yaml, which already defines
msi-parent and has a reference to pci-bus.yaml schema.  Drop redundant
pieces here to make it a bit smaller.

[PATCH 2/3] dt-bindings: PCI: mediatek,mt7621: add missing child node reg

[Krzysztof Kozlowski]

MT7621 PCI host bridge has children which apparently are also PCI host
bridges, at least that's what the binding suggest.  The children have
"reg" property, but do not explicitly define it.  Instead they rely on
pci-bus.yaml schema, but that one has "reg" without any constraints.

Define the "reg" for the children, so the binding will be more specific
and later will allow dropping reference to deprecated pci-bus.yaml
schema.

[PATCH 3/3] dt-bindings: PCI: host-bridges: switch from deprecated pci-bus.yaml

[Krzysztof Kozlowski]

dtschema package with core schemas deprecated pci-bus.yaml schema in
favor of pci-host-bridge.yaml.  Update all bindings to use the latter
one.

The difference between pci-bus.yaml and pci-host-bridge.yaml is only in
lack of "reg" property defined by the latter, which should not have any
effect here, because all these bindings define the "reg".

The change is therefore quite trivial, except mediatek,mt7621-pcie.yaml
binding which have children nodes being also host bridges, apparently.

I think this one should be pci-pci-bridge.yaml instead since it says 
these are root ports and based on the unit-address here.

I was thinking about this as well, but pci-pci-bridge.yaml defines
compatible which is not present here at all. Since you suggest pci-pci,
I'll go with this and make it a separate patch for easier review.

This was my concern at first. It does define compatible, but it
doesn't require it. So I think we are fine.

This implicitly bumps the minimum version for dtschema. That's fine, but 
it should be explicit since we set it explicitly.
