1* Mediatek/Ralink RT3883 PCI controller
2
31) Main node
4
5 Required properties:
6
7 - compatible: must be "ralink,rt3883-pci"
8
9 - reg: specifies the physical base address of the controller and
10 the length of the memory mapped region.
11
12 - #address-cells: specifies the number of cells needed to encode an
13 address. The value must be 1.
14
15 - #size-cells: specifies the number of cells used to represent the size
16 of an address. The value must be 1.
17
18 - ranges: specifies the translation between child address space and parent
19 address space
20
21 Optional properties:
22
23 - status: indicates the operational status of the device.
24 Value must be either "disabled" or "okay".
25
262) Child nodes
27
28 The main node must have two child nodes which describes the built-in
29 interrupt controller and the PCI host bridge.
30
31 a) Interrupt controller:
32
33 Required properties:
34
35 - interrupt-controller: identifies the node as an interrupt controller
36
37 - #address-cells: specifies the number of cells needed to encode an
38 address. The value must be 0. As such, 'interrupt-map' nodes do not
39 have to specify a parent unit address.
40
41 - #interrupt-cells: specifies the number of cells needed to encode an
42 interrupt source. The value must be 1.
43
44 - interrupt-parent: the phandle for the interrupt controller that
45 services interrupts for this device.
46
47 - interrupts: specifies the interrupt source of the parent interrupt
48 controller. The format of the interrupt specifier depends on the
49 parent interrupt controller.
50
51 b) PCI host bridge:
52
53 Required properties:
54
55 - #address-cells: specifies the number of cells needed to encode an
56 address. The value must be 0.
57
58 - #size-cells: specifies the number of cells used to represent the size
59 of an address. The value must be 2.
60
61 - #interrupt-cells: specifies the number of cells needed to encode an
62 interrupt source. The value must be 1.
63
64 - device_type: must be "pci"
65
66 - bus-range: PCI bus numbers covered
67
68 - ranges: specifies the ranges for the PCI memory and I/O regions
69
70 - interrupt-map-mask,
71 - interrupt-map: standard PCI properties to define the mapping of the
72 PCI interface to interrupt numbers.
73
74 The PCI host bridge node migh have additional sub-nodes representing
75 the onboard PCI devices/PCI slots. Each such sub-node must have the
76 following mandatory properties:
77
78 - reg: used only for interrupt mapping, so only the first four bytes
79 are used to refer to the correct bus number and device number.
80
81 - device_type: must be "pci"
82
83 If a given sub-node represents a PCI bridge it must have following
84 mandatory properties as well:
85
86 - #address-cells: must be set to <3>
87
88 - #size-cells: must set to <2>
89
90 - #interrupt-cells: must be set to <1>
91
92 - interrupt-map-mask,
93 - interrupt-map: standard PCI properties to define the mapping of the
94 PCI interface to interrupt numbers.
95
96 Besides the required properties the sub-nodes may have these optional
97 properties:
98
99 - status: indicates the operational status of the sub-node.
100 Value must be either "disabled" or "okay".
