The TUSB7320 supports up to two downstream ports, and the TUSB7340 supports up to four. It includes a feature to configure the polarity of the PWRONx# signals, which are used to control other peripherals. In some systems, the default polarity needs to be inverted, which is supported by the hardware through software configuration. This patch series introduces TUSB73x0 PCIe device tree bindings and modifies the USB XHCI PCI driver to handle PWRONx# polarity via a device tree property.
