1 HiSilicon Hip05 and Hip06 PCIe host bridge DT description
3 HiSilicon PCIe host controller is based on Designware PCI core.
4 It shares common functions with PCIe Designware core driver and inherits
5 common properties defined in
6 Documentation/devicetree/bindings/pci/designware-pci.txt.
8 Additional properties are described here:
11 - compatible: Should contain "hisilicon,hip05-pcie" or "hisilicon,hip06-pcie".
12 - reg: Should contain rc_dbi, config registers location and length.
13 - reg-names: Must include the following entries:
14 "rc_dbi": controller configuration registers;
15 "config": PCIe configuration space registers.
16 - msi-parent: Should be its_pcie which is an ITS receiving MSI interrupts.
17 - port-id: Should be 0, 1, 2 or 3.
20 - status: Either "ok" or "disabled".
21 - dma-coherent: Present if DMA operations are coherent.
23 Hip05 Example (note that Hip06 is the same except compatible):
25 compatible = "hisilicon,hip05-pcie", "snps,dw-pcie";
26 reg = <0 0xb0080000 0 0x10000>, <0x220 0x00000000 0 0x2000>;
27 reg-names = "rc_dbi", "config";
29 msi-parent = <&its_pcie>;
34 ranges = <0x82000000 0 0x00000000 0x220 0x00000000 0 0x10000000>;
37 #interrupt-cells = <1>;
38 interrupt-map-mask = <0xf800 0 0 7>;
39 interrupt-map = <0x0 0 0 1 &mbigen_pcie 1 10
40 0x0 0 0 2 &mbigen_pcie 2 11
41 0x0 0 0 3 &mbigen_pcie 3 12
42 0x0 0 0 4 &mbigen_pcie 4 13>;
