-----Original Message-----You may use the `get_bdf_from_realpath` in Yu-chu's series for converting a path to sysfs device node to BDF. Also, since this method has nothing to do with whether the serial port is using I/O ports or MMIO, also replace iomem2bdf with that method and rewrite its name to be more general, e.g., `ttys_to_bdf`. +

So board inspector should get it separately. +
