+HiSilicon Hip06/Hip07 PCIe host bridge DT (almost ecam) description
+The properties and their meanings are identical to those described in
+host-generic-pci.txt except as listed below.
+
+Properties of the host controller node that differ from
+host-generic-pci.txt:
+
+- compatible     : Must be "hisilicon,pcie-almost-ecam"
+
+- reg            : Two entries: First the ECAM configuration space for any
+		   other bus underneath the root bus. Second, the base
+		   and size of the HiSilicon host bridge registers inculde
+		   the RC itself config space.
+
+Example:
+	pcie0: pcie@a0090000 {
+		compatible = "hisilicon,pcie-almost-ecam";
+		reg = <0 0xb0000000 0 0x2000000>,  /*  ECAM configuration space */
+		      <0 0xa0090000 0 0x10000>; /* host bridge registers */
+		bus-range = <0  31>;
+		msi-map = <0x0000 &its_dsa 0x0000 0x2000>;
+		msi-map-mask = <0xffff>;
