1Sigma Designs Tango PCIe controller
2
3Required properties:
4
5- compatible: "sigma,smp8759-pcie"
6- reg: address/size of PCI configuration space, address/size of register area
7- bus-range: defined by size of PCI configuration space
8- device_type: "pci"
9- #size-cells: <2>
10- #address-cells: <3>
11- msi-controller
12- ranges: translation from system to bus addresses
13- interrupts: spec for misc interrupts, spec for MSI

15Example:
16
17 pcie@2e000 {
18 compatible = "sigma,smp8759-pcie";
19 reg = <0x50000000 0x400000>, <0x2e000 0x100>;
20 bus-range = <0 3>;
21 device_type = "pci";
22 #size-cells = <2>;
23 #address-cells = <3>;
24 msi-controller;
25 ranges = <0x02000000 0x0 0x00400000 0x50400000 0x0 0x3c00000>;
26 interrupts =
27 <54 IRQ_TYPE_LEVEL_HIGH>, /* misc interrupts */
28 <55 IRQ_TYPE_LEVEL_HIGH>; /* MSI */
29 };
