-* Freescale Serial RapidIO (SRIO) Controller
-
-RapidIO port node:
-Properties:
- - compatible
- Usage: required
- Value type: <string>
- Definition: Must include "fsl,srio" for IP blocks with IP Block
- Revision Register (SRIO IPBRR1) Major ID equal to 0x01c0.
-
- Optionally, a compatiable string of "fsl,srio-vX.Y" where X is Major
- version in IP Block Revision Register and Y is Minor version. 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>;
- };
- };
