SA8775P is currently reusing the PID 0x0306 (the default one hardcoded in the config space header) as the unique PID is not yet allocated. But the host side stack works fine with the default PID. It will get updated once the PID is finalized. Currently, it has no fixed PCI class, so it is being advertised as "PCI_CLASS_OTHERS".
