Microchip PCI1XXXX is an unmanaged PCIe3.1a switch for consumer, industrial, and automotive applications. This switch has multiple downstream ports. One of the switch's downstream ports is a multifunction endpoint; one of those functions supports SPI functionality. This series of patches provides the SPI controller driver for the SPI function of the multifunction PCIe endpoint of the switch.
