If this - compatiable is provided it should be ordered before "fsl,srio". - - - reg - Usage: required - Value type: <prop-encoded-array> - Definition: A standard property. Specifies the physical address and - length of the SRIO configuration registers. The size should - be set to 0x11000. - - - interrupts - Usage: required - Value type: <prop_encoded-array> - Definition: Specifies the interrupts generated by this device. The - value of the interrupts property consists of one interrupt - specifier. The format of the specifier is defined by the - binding document describing the node's interrupt parent. - - A single IRQ that handles error conditions is specified by this - property. (Typically shared with port-write). - - - fsl,srio-rmu-handle: - Usage: required if rmu node is defined - Value type: <phandle> - Definition: A single <phandle> value that points to the RMU. - (See srio-rmu.txt for more details on RMU node binding) - -Port Child Nodes: There should a port child node for each port that exists in -the controller. The ports are numbered starting at one (1) and should have -the following properties: - - - cell-index - Usage: required - Value type: <u32> - Definition: A standard property. Matches the port id. - - - ranges - Usage: required if local access windows preset - Value type: <prop-encoded-array> - Definition: A standard property. Utilized to describe the memory mapped - IO space utilized by the controller. This corresponds to the - setting of the local access windows that are targeted to this - SRIO port. - - - fsl,liodn - Usage: optional-but-recommended (for devices with PAMU) - Value type: <prop-encoded-array> - Definition: The logical I/O device number for the PAMU (IOMMU) to be - correctly configured for SRIO accesses. The property should - not exist on devices that do not support PAMU. - - For HW (ie, the P4080) that only supports a LIODN for both - memory and maintenance transactions then a single LIODN is - represented in the property for both transactions. - - For HW (ie, the P304x/P5020, etc) that supports an LIODN for - memory transactions and a unique LIODN for maintenance - transactions then a pair of LIODNs are represented in the - property. Within the pair, the first element represents the - LIODN associated with memory transactions and the second element - represents the LIODN associated with maintenance transactions - for the port. - -Note: All other standard properties (see ePAPR) are allowed but are optional. - -Example: - - rapidio: rapidio@ffe0c0000 { - #address-cells = <2>; - #size-cells = <2>; - reg = <0xf 0xfe0c0000 0 0x11000>; - compatible = "fsl,srio"; - interrupts = <16 2 1 11>; /* err_irq */ - fsl,srio-rmu-handle = <&rmu>; - ranges; - - port1 { - cell-index = <1>; - #address-cells = <2>; - #size-cells = <2>; - fsl,liodn = <34>; - ranges = <0 0 0xc 0x20000000 0 0x10000000>; - }; - - port2 { - cell-index = <2>; - #address-cells = <2>; - #size-cells = <2>; - fsl,liodn = <48>; - ranges = <0 0 0xc 0x30000000 0 0x10000000>; - }; - }; |
