At this point, the primary consumer for these bindings is U-Boot. With the help of these bindings U-Boot can bring up the PCIe root complex into a state where the OS use it without having to deal with the GPIO pins. A Linux driver may be implemented later to support power management and/or other devices that need GPIO control. Since the binding is based on standard pinmux node bindings this should be relatively easy.
