Most my comments from TAM3517 are still valid for this module. I post
here only new comments ;-)
I think you have already got the comment, but you should better explain
in the commit message what the patch does. This patch is different from
the TAM3517 patch, but both share the same commit message.

The correct and used way is to set author and copyright in the header
file, and put the maintainer name in the MAINTAINER file.

You have already used the GPIO framework - why do you write directly the
registers ?
This should be fixed globally.

mmmhh...memory is computed with get_ram_size(), not on the revision number.
