A mechanism is required to associate a device with both the MSI +controllers it can address, and the sideband data that will be associated with +its writes to those controllers. + +For generic MSI bindings, see +Documentation/devicetree/bindings/interrupt-controller/msi.txt. + + +PCI root complex +================ + +Optional properties +------------------- + +- msi-map: Maps a Requester ID to an MSI controller and associated + msi-specifier data. The property is an arbitrary number of tuples of + (rid-base,msi-controller,msi-base,length), where: + + * rid-base is a single cell describing the first RID matched by the entry. + + * msi-controller is a single phandle to an MSI controller + + * msi-base is an msi-specifier describing the msi-specifier produced for the + first RID matched by the entry. + + * length is a single cell describing how many consecutive RIDs are matched + following the rid-base. + + Any RID r in the interval [rid-base, rid-base + length) is associated with + the listed msi-controller, with the msi-specifier (r - rid-base + msi-base). + +- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped + to an msi-specifier per the msi-map property. + +- msi-parent: Describes the MSI parent of the root complex itself. Where + the root complex and MSI controller do not pass sideband data with MSI + writes, this property may be used to describe the MSI controller(s) + used by PCI devices under the root complex, if defined as such in the + binding for the root complex. + + +Example (1) +=========== + +/ { + #address-cells = <1>; + #size-cells = <1>; + + msi: msi-controller@a { + reg = <0xa 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + pci: pci@f { + reg = <0xf 0x1>; + compatible = "vendor,pcie-root-complex"; + device_type = "pci"; + + /* + * The sideband data provided to the MSI controller is + * the RID, identity-mapped. + */ + msi-map = <0x0 &msi_a 0x0 0x10000>, + }; +}; + + +Example (2) +=========== + +/ { + #address-cells = <1>; + #size-cells = <1>; + + msi: msi-controller@a { + reg = <0xa 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + pci: pci@f { + reg = <0xf 0x1>; + compatible = "vendor,pcie-root-complex"; + device_type = "pci"; + + /* + * The sideband data provided to the MSI controller is + * the RID, masked to only the device and function bits. + */ + msi-map = <0x0 &msi_a 0x0 0x100>, + msi-map-mask = <0xff> + }; +}; + + +Example (3) +=========== + +/ { + #address-cells = <1>; + #size-cells = <1>; + + msi: msi-controller@a { + reg = <0xa 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + pci: pci@f { + reg = <0xf 0x1>; + compatible = "vendor,pcie-root-complex"; + device_type = "pci"; + + /* + * The sideband data provided to the MSI controller is + * the RID, but the high bit of the bus number is + * ignored. + */ + msi-map = <0x0000 &msi 0x0000 0x8000>, + <0x8000 &msi 0x0000 0x8000>; + }; +}; + + +Example (4) +=========== + +/ { + #address-cells = <1>; + #size-cells = <1>; + + msi: msi-controller@a { + reg = <0xa 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + pci: pci@f { + reg = <0xf 0x1>; + compatible = "vendor,pcie-root-complex"; + device_type = "pci"; + + /* + * The sideband data provided to the MSI controller is + * the RID, but the high bit of the bus number is + * negated. + */ + msi-map = <0x0000 &msi 0x8000 0x8000>, + <0x8000 &msi 0x0000 0x8000>; + }; +}; + + +Example (5) +=========== + +/ { + #address-cells = <1>; + #size-cells = <1>; + + msi_a: msi-controller@a { + reg = <0xa 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + msi_b: msi-controller@b { + reg = <0xb 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + msi_c: msi-controller@c { + reg = <0xc 0x1>; + compatible = "vendor,some-controller"; + msi-controller; + #msi-cells = <1>; + }; + + pci: pci@c { + reg = <0xf 0x1>; + compatible = "vendor,pcie-root-complex"; + device_type = "pci"; + + /* + * The sideband data provided to MSI controller a is the + * RID, but the high bit of the bus number is negated. + * The sideband data provided to MSI controller b is the + * RID, identity-mapped. + * MSI controller c is not addressable. + */ + msi-map = <0x0000 &msi_a 0x8000 0x08000>, + <0x8000 &msi_a 0x0000 0x08000>, + <0x0000 &msi_b 0x0000 0x10000>; + }; +}; diff --git a/kernel/Documentation/devicetree/bindings/pci/pci-rcar-gen2.txt b/kernel/Documentation/devicetree/bindings/pci/pci-rcar-gen2.txt index d8ef5bf50..7fab84b33 100644 --- a/kernel/Documentation/devicetree/bindings/pci/pci-rcar-gen2.txt +++ b/kernel/Documentation/devicetree/bindings/pci/pci-rcar-gen2.txt @@ -7,7 +7,8 @@ OHCI and EHCI controllers.
