+The HiP05 PCIe-SAS system controller is shared by PCIe and SAS controllers in
+HiP05 Soc to implement some basic configurations.

+HiSilicon PCIe host bridge DT description
+
+HiSilicon PCIe host controller is based on Designware PCI core.
+It shares common functions with PCIe Designware core driver and inherits
+common properties defined in
+Documentation/devicetree/bindings/pci/designware-pci.txt.
+
+Additional properties are described here:
+
+Required properties:
+- compatible: Should contain "hisilicon,hip05-pcie".
+- reg: Should contain rc_dbi, config registers location and length.
+- reg-names: Must include the following entries:
+  "rc_dbi": controller configuration registers;
+  "config": PCIe configuration space registers.
+- msi-parent: Should be its_pcie which is an ITS receiving MSI interrupts.
+- port-id: Should be 0, 1, 2 or 3.
+
+Optional properties:
+- status: Either "ok" or "disabled".
+- dma-coherent: Present if DMA operations are coherent.
+
+Example:
+	pcie@0xb0080000 {
+		compatible = "hisilicon,hip05-pcie", "snps,dw-pcie";
+		reg = <0 0xb0080000 0 0x10000>, <0x220 0x00000000 0 0x2000>;
