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. > Do you have a working pre-release version somewhere? Sorry, nothing started, yet. Are you going to work on it? If so, feel free to involve me in patches and reviews.
