+HiSilicon STB PCIe host bridge DT description
+
+HiSilicon STB PCIe host controller is based on DesignWare PCIe core.
+It shares common functions with PCIe DesignWare core driver and inherits
+common properties defined in
+Documentation/devicetree/bindings/pci/designware-pcie.txt.
+
+Additional properties are described here:
+
+Required properties
+- compatible: Should be one of the following strings:
+		"hisilicon,hi3798cv200-pcie"
+- reg: Should contain sysctl, rc_dbi, config registers location and length.
+- reg-names: Must include the following entries:
+  "control": control registers of PCIe controller;
+  "rc-dbi": configuration space of PCIe controller;
+  "config": configuration transaction space of PCIe controller.
+- bus-range: PCI bus numbers covered.
+- interrupts: MSI interrupt.
+- interrupt-names: Must include "msi" entries.
+- clocks: List of phandle and clock specifier pairs as listed in clock-names
+  property.
+- clock-name: Must include the following entries:
+  "aux": auxiliary gate clock;
+  "pipe": pipe gate clock;
+  "sys": sys gate clock;
+  "bus": bus gate clock.
+- resets: List of phandle and reset specifier pairs as listed in reset-names
+  property.
+- reset-names: Must include the following entries:
+  "soft": soft reset;
+  "sys": sys reset;
+  "bus": bus reset.
+
+Optional properties:
+- reset-gpios: The gpio to generate PCIe PERST# assert and deassert signal.
+- phys: List of phandle and phy mode specifier, should be 0.
+- phy-names: Must be "phy".
+
+Example:
+	pcie@f9860000 {
+		compatible = "hisilicon,hi3798cv200-pcie";
