Thanks for your patch!

While this driver uses ins[bw](), this seems unrelated to legacy
I/O space, as the driver maps a MMIO region. Probably different
accessors should be used instead.
Note that this driver has no in-tree users. Same for the SPI variant,
but at least that one has modern json-schema DT bindings ;-)

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
