I seem to get warning for "reg_format" even after adding address-cells and size-cells property in epf_bus. Can you give some hints here please? > +epf,vendor-id = /bits/ 16 <0x104c>; I want to make vendor-id and device-id as 16 bits from the beginning at-least for PCIe endpoint. So I'm prefixing these properties with "epf,". However I get this "do not match any of the regexes:". Can we add "epf" as a standard prefix?

[PATCH 01/19] dt-bindings: PCI: Endpoint: Add DT bindings for PCI EPF NTB Device
Add device tree schema for PCI endpoint function bus to which endpoint function devices should be attached. Then add device tree schema for PCI endpoint function device to include bindings thats generic to all endpoint functions. Finally add device tree schema for PCI endpoint NTB function device by including the generic device tree schema for PCIe endpoint function.
