1* Freescale Serial RapidIO (SRIO) Controller2 3RapidIO port node:4Properties:5 - compatible6 Usage: required7 Value type: <string>8 Definition: Must include "fsl,srio" for IP blocks with IP Block9 Revision Register (SRIO IPBRR1) Major ID equal to 0x01c0.10 11 Optionally, a compatible string of "fsl,srio-vX.Y" where X is Major12 version in IP Block Revision Register and Y is Minor version. If this13 compatible is provided it should be ordered before "fsl,srio".14 15 - reg16 Usage: required17 Value type: <prop-encoded-array>18 Definition: A standard property. Specifies the physical address and19 length of the SRIO configuration registers. The size should20 be set to 0x11000.21 22 - interrupts23 Usage: required24 Value type: <prop_encoded-array>25 Definition: Specifies the interrupts generated by this device. The26 value of the interrupts property consists of one interrupt27 specifier. The format of the specifier is defined by the28 binding document describing the node's interrupt parent.29 30 A single IRQ that handles error conditions is specified by this31 property. (Typically shared with port-write).32 33 - fsl,srio-rmu-handle:34 Usage: required if rmu node is defined35 Value type: <phandle>36 Definition: A single <phandle> value that points to the RMU.37 (See srio-rmu.txt for more details on RMU node binding)38 39Port Child Nodes: There should a port child node for each port that exists in40the controller. The ports are numbered starting at one (1) and should have41the following properties:42 43 - cell-index44 Usage: required45 Value type: <u32>46 Definition: A standard property. Matches the port id.47 48 - ranges49 Usage: required if local access windows preset50 Value type: <prop-encoded-array>51 Definition: A standard property. Utilized to describe the memory mapped52 IO space utilized by the controller. This corresponds to the53 setting of the local access windows that are targeted to this54 SRIO port.55 56 - fsl,liodn57 Usage: optional-but-recommended (for devices with PAMU)58 Value type: <prop-encoded-array>59 Definition: The logical I/O device number for the PAMU (IOMMU) to be60 correctly configured for SRIO accesses. The property should61 not exist on devices that do not support PAMU.62 63 For HW (ie, the P4080) that only supports a LIODN for both64 memory and maintenance transactions then a single LIODN is65 represented in the property for both transactions.66 67 For HW (ie, the P304x/P5020, etc) that supports an LIODN for68 memory transactions and a unique LIODN for maintenance69 transactions then a pair of LIODNs are represented in the70 property. Within the pair, the first element represents the71 LIODN associated with memory transactions and the second element72 represents the LIODN associated with maintenance transactions73 for the port.74 75Note: All other standard properties (see the Devicetree Specification)76are allowed but are optional.77 78Example:79 80 rapidio: rapidio@ffe0c0000 {81 #address-cells = <2>;82 #size-cells = <2>;83 reg = <0xf 0xfe0c0000 0 0x11000>;84 compatible = "fsl,srio";85 interrupts = <16 2 1 11>; /* err_irq */86 fsl,srio-rmu-handle = <&rmu>;87 ranges;88 89 port1 {90 cell-index = <1>;91 #address-cells = <2>;92 #size-cells = <2>;93 fsl,liodn = <34>;94 ranges = <0 0 0xc 0x20000000 0 0x10000000>;95 };96 97 port2 {98 cell-index = <2>;99 #address-cells = <2>;100 #size-cells = <2>;101 fsl,liodn = <48>;102 ranges = <0 0 0xc 0x30000000 0 0x10000000>;103 };104 };105
