+Many of the Gateworks Ventana boards use a PLX PEX860X PCIe Switch
+and utilize its GPIO outputs as PERST# for downstream ports. This
+patch configures them appropriately during enumeration.
+
+Additionally many of the Ventana boards use CKO1 as the clock input for
+an analog audio codec which is setup here.
