Cadence themselves have a validation platform for validating the PCIe IP which is already in the upstream kernel. Right now the binding only exists for Cadence platform and this will result in adding redundant binding schema for any platform using Cadence PCIe core. This series: 1) Create cdns-pcie.yaml which includes properties that are applicable to both host mode and endpoint mode of Cadence PCIe core. 2) Create cdns-pcie-host.yaml to include properties that are specific to host mode of Cadence PCIe core. cdns-pcie-host.yaml will include cdns-pcie.yaml. 3) Create cdns-pcie-ep.yaml to include properties that are specific to endpoint mode of Cadence PCIe core. cdns-pcie-ep.yaml will include cdns-pcie.yaml. 4) Remove cdns,cdns-pcie-ep.txt and cdns,cdns-pcie-host.txt which had the binding for Cadence "platform" and add cdns,cdns-pcie-host.yaml and cdns,cdns-pcie-ep.yaml schema for Cadence Platform. The schema for Cadence platform then includes schema for Cadence PCIe core. Changes from v2: *) Created "pci-ep.yaml" for common endpoint controller bindings *) Deprecate "cdns,max-outbound-regions" and "cdns,no-bar-match-nbits" binding Changes from v1: *) Fix maximum values of num-lanes and cdns,no-bar-match-nbits *) Fix example DT node for PCIe Endpoint.
