    1 * Bus Enumeration by Freescale PCI-X Agent
    2 
    3 Typically any Freescale PCI-X bridge hardware strapped into Agent mode
    4 is prevented from enumerating the bus. The PrPMC form-factor requires
    5 all mezzanines to be PCI-X Agents, but one per system may still
    6 enumerate the bus.
    7 
    8 The property defined below will allow a PCI-X bridge to be used for bus
    9 enumeration despite being strapped into Agent mode.
   10 
   11 Required properties:
   12 - fsl,pci-agent-force-enum : There is no value associated with this
   13   property. The property itself is treated as a boolean.
   14 
   15 Example:
   16 
   17         /* PCI-X bridge known to be PrPMC Monarch */
   18         pci0: pci@ef008000 {
   19                 fsl,pci-agent-force-enum;
   20                 #interrupt-cells = <1>;
   21                 #size-cells = <2>;
   22                 #address-cells = <3>;
   23                 compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci";
   24                 device_type = "pci";
   25                 ...
   26                 ...
   27         };
