I think you maybe misunderstood my previous mail, or I misunderstood yours :)

Make sure that passthrough mode is set up in the .set_config() callback,
nothing else.

Do not change the signatures of the direction functions or set_value()
functions in gpiolib.

But maybe you are talking about implementation details in the specific
GPIO driver for Aspeed? Then I just missed that part, sorry.

Yours,
