Sascha,
I know DW's GPIO is also used on Armada 1500 which I currently work on.
Precisely, the IP is named dw-apb-gpio. Maybe the above should also
reflect APB.
[...]
Please add "snps,dw-apb-gpio", that's what the linux driver
will look for if make to pick it up for Armada 1500.
Are you talking about the 'old' linux driver that was posted sometime around
January 2012 or are you working on your own?
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.
Sebastian
