+    description: Each family of socfpga has its own implementation of the
+      PCI controller. The altr,pcie-root-port-1.0 is used for the Cyclone5
+      family of chips. The Stratix10 family of chips is supported by the
+      altr,pcie-root-port-2.0. The Agilex family of chips has three,
+      non-register compatible, variants of PCIe Hard IP referred to as the
+      F-Tile, P-Tile, and R-Tile, depending on the specific chip instance.
