Hm. Is this really generic? Well I guess of more and more
SoC's get pin controllers in front of their GPIOs then yes. But
for an off-chip GPIO expander this is not really "generic".

Second argument should be named "offset", "gpio" is ambigous
someone could think it's the global GPIO number.
Please collect the various ACKs and I will apply the patch series.
I have another comment which will be more of a discussion and
possible further improvement.
Yours,
