1 | Message unit node: | ||
2 | |||
3 | For SRIO controllers that implement the message unit as part of the controller | ||
4 | this node is required. For devices with RMAN this node should NOT exist. The | ||
5 | node is composed of three types of sub-nodes ("fsl-srio-msg-unit", | ||
6 | "fsl-srio-dbell-unit" and "fsl-srio-port-write-unit"). | ||
7 | |||
8 | See srio.txt for more details about generic SRIO controller details. | ||

13 | Definition: Must include "fsl,srio-rmu-vX.Y", "fsl,srio-rmu". | ||
14 | |||
15 | The version X.Y should match the general SRIO controller's IP Block | ||
16 | revision register's Major(X) and Minor (Y) value. | ||
17 | |||
18 | - reg | ||
19 | Usage: required | ||
20 | Value type: <prop-encoded-array> | ||
21 | Definition: A standard property. Specifies the physical address and | ||
22 | length of the SRIO configuration registers for message units | ||
23 | and doorbell units. | ||
24 | |||
25 | - fsl,liodn | ||
26 | Usage: optional-but-recommended (for devices with PAMU) | ||
27 | Value type: <prop-encoded-array> | ||
28 | Definition: The logical I/O device number for the PAMU (IOMMU) to be | ||
29 | correctly configured for SRIO accesses. The property should | ||
30 | not exist on devices that do not support PAMU. | ||
31 | |||
32 | The LIODN value is associated with all RMU transactions | ||
33 | (msg-unit, doorbell, port-write). | ||
34 | |||
35 | Sub-Nodes for RMU: The RMU node is composed of multiple sub-nodes that | ||
36 | correspond to the actual sub-controllers in the RMU. The manual for a given | ||
37 | SoC will detail which and how many of these sub-controllers are implemented. | ||

56 | - interrupts | ||
57 | Usage: required | ||
58 | Value type: <prop_encoded-array> | ||
59 | Definition: Specifies the interrupts generated by this device. The | ||
60 | value of the interrupts property consists of one interrupt | ||
61 | specifier. The format of the specifier is defined by the | ||
62 | binding document describing the node's interrupt parent. | ||
63 | |||
64 | A pair of IRQs are specified in this property. The first | ||
65 | element is associated with the transmit (TX) interrupt and the | ||
66 | second element is associated with the receive (RX) interrupt. | ||

89 | Definition: Specifies the interrupts generated by this device. The | ||
90 | value of the interrupts property consists of one interrupt | ||
91 | specifier. The format of the specifier is defined by the | ||
92 | binding document describing the node's interrupt parent. | ||
93 | |||
94 | A pair of IRQs are specified in this property. The first | ||
95 | element is associated with the transmit (TX) interrupt and the | ||
96 | second element is associated with the receive (RX) interrupt. | ||
97 | |||
98 | Port-Write Unit: | ||
99 | |||
100 | - compatible | ||
101 | Usage: required | ||
102 | Value type: <string> | ||

116 | - interrupts | ||
117 | Usage: required | ||
118 | Value type: <prop_encoded-array> | ||
119 | Definition: Specifies the interrupts generated by this device. The | ||
120 | value of the interrupts property consists of one interrupt | ||
121 | specifier. The format of the specifier is defined by the | ||
122 | binding document describing the node's interrupt parent. | ||
123 | |||
124 | A single IRQ that handles port-write conditions is | ||
125 | specified by this property. (Typically shared with error). | ||
126 | |||
127 | Note: All other standard properties (see the ePAPR) are allowed | ||
128 | but are optional. | ||
