No Device Node for Pin Controller of hardware

Hi there,

I am trying to interface Wiznet w5500 module (SPI to Ethernet module) with HiFive Unleashed running linux image generated through Freedom-U-SDK. I have integrated the wiznet driver into my linux image. And I also know that I have to update my device tree in order to let the driver work for w5500 hardware.
While reading device tree binding of wiznet module (Link), I came to know that I have to enter pinctrl-0 entry in my device tree node for wiznet module.

While investigating device tree includes of HiFive Unleashed, I couldn’t find any pin controller node for the hardware (Link) to whom I can reference and add my pins into.

Please help me adding pins for my wiznet module, is there something I am missing?
