Hi Fabio,
This will disable register cache so it isn't right. Could you try REGCACHE_FLAT instead, please?
Yes, with REGCACHE_FLAT I don't get the warning.
Regards,
Is it possible for you to test the following updated patch?

You'll also need to apply regmap fix from http://www.spinics.net/lists/kernel/msg2161934.html to make it work.
Thanks in advance.
