It's pretty much the same remark than for the name of the binding
file, but sunxi in itself is pretty confusing, it covers a range of
SoCs going from armv5 to armv8, some with a single CPU and some with
more, and some with an OpenRISC core and some without.

It would be less confusing (albeit not perfect) to use sun6i there,
the family that IP was first introduced in.
