-TI Keystone PCIe interface
-
-Keystone PCI host Controller is based on the Synopsys DesignWare PCI
-hardware version 3.65. It shares common functions with the PCIe DesignWare
-core driver and inherits common properties defined in
-Documentation/devicetree/bindings/pci/designware-pcie.txt
-
-Please refer to Documentation/devicetree/bindings/pci/designware-pcie.txt
-for the details of DesignWare DT bindings. Additional properties are
-described here as well as properties that are not applicable.
-
-Required Properties:-
-
-compatibility: Should be "ti,keystone-pcie" for RC on Keystone2 SoC
- Should be "ti,am654-pcie-rc" for RC on AM654x SoC
-reg: Three register ranges as listed in the reg-names property
-reg-names: "dbics" for the DesignWare PCIe registers, "app" for the
- TI specific application registers, "config" for the
- configuration space address
-
-pcie_msi_intc : Interrupt controller device node for MSI IRQ chip
- interrupt-cells: should be set to 1
- interrupts: GIC interrupt lines connected to PCI MSI interrupt lines
- (required if the compatible is "ti,keystone-pcie")
-msi-map: As specified in Documentation/devicetree/bindings/pci/pci-msi.txt
- (required if the compatible is "ti,am654-pcie-rc".
-
-ti,syscon-pcie-id : phandle to the device control module required to set device
- id and vendor id.
-ti,syscon-pcie-mode : phandle to the device control module required to configure
- PCI in either RC mode or EP mode.
-
- Example:
- pcie_msi_intc: msi-interrupt-controller {
- interrupt-controller;
- #interrupt-cells = <1>;
- interrupt-parent = <&gic>;
- interrupts = <GIC_SPI 30 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 31 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 32 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 33 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 34 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 35 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 36 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 37 IRQ_TYPE_EDGE_RISING>;
- };
-
-pcie_intc: Interrupt controller device node for Legacy IRQ chip
- interrupt-cells: should be set to 1
-
- Example:
- pcie_intc: legacy-interrupt-controller {
- interrupt-controller;
- #interrupt-cells = <1>;
- interrupt-parent = <&gic>;
- interrupts = <GIC_SPI 26 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 27 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 28 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 29 IRQ_TYPE_EDGE_RISING>;
- };
-
-Optional properties:-
- phys: phandle to generic Keystone SerDes PHY for PCI
- phy-names: name of the generic Keystone SerDes PHY for PCI
- - If boot loader already does PCI link establishment, then phys and
- phy-names shouldn't be present.
- interrupts: platform interrupt for error interrupts.
-
-DesignWare DT Properties not applicable for Keystone PCI
-
-1. pcie_bus clock-names not used. Instead, a phandle to phys is used.
-
-AM654 PCIe Endpoint
-===================
-
-Required Properties:-
-
-compatibility: Should be "ti,am654-pcie-ep" for EP on AM654x SoC
-reg: Four register ranges as listed in the reg-names property
-reg-names: "dbics" for the DesignWare PCIe registers, "app" for the
- TI specific application registers, "atu" for the
- Address Translation Unit configuration registers and
- "addr_space" used to map remote RC address space

-
-Optional properties:-
-
-phys: list of PHY specifiers (used by generic PHY framework)
-phy-names: must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the

unevaluatedProperties is what we want here.

Yes, because unevaluatedProperties is currently unimplemented. Once
the upstream jsonschema tool supports it[1], there will be warnings.
The other way we could address this is there are $ref resolving tools
that flatten schemas.

Is it possible to lock this down further with additionalProperties: false?

I could add some ridiculous property like system-controller; to the
example and the checks wont catch it.

same with the host as well.

Is it possible to lock this down further with additionalProperties: false?

^^ just change this to
reg = <0x5500000 0x1000>,
<0x5501000 0x1000>,
<0x10000000 0x8000000>

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
