dt-bindings: PCI: fsl,imx6q: fix assigned-clocks warning

2023-05-09T06:01:49Z

assigned-clocks are a dependency of clocks, however the dtschema has limitation and expects clocks to be present in the binding using assigned-clocks, not in other referenced bindings. The clocks were defined in common fsl,imx6q-pcie-common.yaml, which is referenced by fsl,imx6q-pcie-ep.yaml. The fsl,imx6q-pcie-ep.yaml used assigned-clocks thus leading to warnings: Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000: Unevaluated properties are not allowed ('assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks' were unexpected) From schema: Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.yaml Fix this by moving clocks to each specific schema from the common one and narrowing them to strictly match what is expected for given device.

dt-bindings: PCI: qcom: Document msi-map and msi-map-mask properties

2023-04-12T13:22:32Z

The Qcom PCIe controller is capable of using either internal MSI controller or the external GIC-ITS for signaling MSIs sent by endpoint devices. Currently, the binding only documents the internal MSI implementation. Let's document the GIC-ITS imeplementation by making use of msi-map and msi-map-mask properties. Only one of the implementation should be used at a time and the drivers can choose the preferred one.
