1* Freescale Serial RapidIO (SRIO) Controller
2
3RapidIO port node:
4Properties:
5   - compatible
6	Usage: required
7	Value type: <string>
8	Definition: Must include "fsl,srio" for IP blocks with IP Block
9	Revision Register (SRIO IPBRR1) Major ID equal to 0x01c0.
10
11	Optionally, a compatible string of "fsl,srio-vX.Y" where X is Major
12	version in IP Block Revision Register and Y is Minor version.  If this
13	compatible is provided it should be ordered before "fsl,srio".
14
15   - reg
16	Usage: required
17	Value type: <prop-encoded-array>
18	Definition: A standard property.  Specifies the physical address and
19		length of the SRIO configuration registers.  The size should
20		be set to 0x11000.
21
22   - interrupts
23	Usage: required
24	Value type: <prop_encoded-array>
25	Definition:  Specifies the interrupts generated by this device.  The
26		value of the interrupts property consists of one interrupt
27		specifier. The format of the specifier is defined by the
28		binding document describing the node's interrupt parent.
29
30		A single IRQ that handles error conditions is specified by this
31		property.  (Typically shared with port-write).
32
33   - fsl,srio-rmu-handle:
34	Usage: required if rmu node is defined
35	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 in
40the controller.  The ports are numbered starting at one (1) and should have
41the following properties:
42
43   - cell-index
44	Usage: required
45	Value type: <u32>
46	Definition: A standard property.  Matches the port id.
47
48   - ranges
49	Usage: required if local access windows preset
50	Value type: <prop-encoded-array>
51	Definition: A standard property. Utilized to describe the memory mapped
52		IO space utilized by the controller.  This corresponds to the
53		setting of the local access windows that are targeted to this
54		SRIO port.
55
56   - fsl,liodn
57	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 be
60		correctly configured for SRIO accesses.  The property should
61		not exist on devices that do not support PAMU.
62
63		For HW (ie, the P4080) that only supports a LIODN for both
64		memory and maintenance transactions then a single LIODN is
65		represented in the property for both transactions.
66
67		For HW (ie, the P304x/P5020, etc) that supports an LIODN for
68		memory transactions and a unique LIODN for maintenance
69		transactions then a pair of LIODNs are represented in the
70		property.  Within the pair, the first element represents the
71		LIODN associated with memory transactions and the second element
72		represents the LIODN associated with maintenance transactions
73		for the port.
74
75Note: All other standard properties (see ePAPR) are allowed but are optional.
