7    - compatible: must be "ralink,rt3883-pci"
9    - reg: specifies the physical base address of the controller and
12    - #address-cells: specifies the number of cells needed to encode an
15    - #size-cells: specifies the number of cells used to represent the size
18    - ranges: specifies the translation between child address space and parent
23    - status: indicates the operational status of the device.
26 2) Child nodes
28    The main node must have two child nodes which describes the built-in
29    interrupt controller and the PCI host bridge.
31    a) Interrupt controller:
35    - interrupt-controller: identifies the node as an interrupt controller
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
41    - #interrupt-cells: specifies the number of cells needed to encode an
42      interrupt source. The value must be 1.
44    - interrupts: specifies the interrupt source of the parent interrupt
45      controller. The format of the interrupt specifier depends on the
46      parent interrupt controller.
52    - #address-cells: specifies the number of cells needed to encode an
55    - #size-cells: specifies the number of cells used to represent the size
58    - #interrupt-cells: specifies the number of cells needed to encode an
59      interrupt source. The value must be 1.
61    - device_type: must be "pci"
63    - bus-range: PCI bus numbers covered
65    - ranges: specifies the ranges for the PCI memory and I/O regions
67    - interrupt-map-mask,
68    - interrupt-map: standard PCI properties to define the mapping of the
69      PCI interface to interrupt numbers.
71    The PCI host bridge node might have additional sub-nodes representing
72    the onboard PCI devices/PCI slots. Each such sub-node must have the
75      - reg: used only for interrupt mapping, so only the first four bytes
78      - device_type: must be "pci"
80    If a given sub-node represents a PCI bridge it must have following
83      - #address-cells: must be set to <3>
85      - #size-cells: must set to <2>
87      - #interrupt-cells: must be set to <1>
89      - interrupt-map-mask,
90      - interrupt-map: standard PCI properties to define the mapping of the
91        PCI interface to interrupt numbers.
93    Besides the required properties the sub-nodes may have these optional
96      - status: indicates the operational status of the sub-node.
