I figured those patches were lost behind and started just yesterday to
revitalize Jamies work. Although, I think the bank stuff doesn't seem
necessary as the core knows all that stuff by itself AFAIK.
But, I don't have access to the Synopsys datasheet and must go by what
I can make out of the hps.html (which is really inconvenient to use if you
ask me).

Do you have that updated driver somewhere to look at? Maybe I can then just
do something else. The gpio-dw.c from rocketboards/socfpga-3.11 doesn't look
like it is based on Jamies work.

Regards,
Steffen
