Cannot recall the actual version or time posted. I didn't find time to
work on a linux driver for dw-apb-gpio, yet. My idea was to pick up the
latest driver posted plus make it more general. IIRC the one posted was
very limited to socfpga.

Are you going to work on it? If so, feel free to involve me in patches
and reviews.
