However it failed to set the mode for "ti,keystone-pcie" compatible. Since the mode defaults to "DW_PCIE_UNKNOWN_TYPE", the following error message is displayed for the v3.65a controller: "INVALID device type 0" Despite the driver probing successfully, the controller may not be functional in the Root Complex mode of operation. So, set the mode as Root Complex for "ti,keystone-pcie" compatible to fix this.
