Hi Maxime,

Sorry I hadn't looked at the new driver before, but I did now and need a little
clarification. It seems to me that the device should be compatible with the
generic DT binding we have in Documentation/devicetree/bindings/misc/sram.txt,
and use more generic code. At least I can't see much in here that is really sunxi

Were you not aware of that generic binding, or did you have a good reason
not to use it? In the latter case, please document that in the patch description
(after replying here).

One small bug I found in the DT binding: the main DT node is lacking
a "ranges" property.
